In the modern landscape of music, where digital production often prioritizes layers of complexity and rapid-fire shifts, there is a profound, quiet rebellion in the act of standing still.
In the latest single from Erin McCallum, taken from her forthcoming album, we are presented with a singular, striking image: McCallum behind bars, clinging to the cold iron of a jail cell with stark cinematic intensity. But the real confinement isn’t found in the artwork; it lies within the music itself. Co-written with long-time collaborator and guitarist Teddy Leonard, this track is a masterclass in the one-chord tradition.
To the uninitiated, a one-chord song might seem like a limitation. To the historian and the student of unvarnished roots traditions, it is a definitive statement of discipline. From the trance-inducing desert blues of the Sahara to the stomping, unyielding boogies of the Mississippi Delta, the singular chord is a cultural thread that binds the Atlantic diaspora. It is an “infinite one,” a foundation that forces the writing partnership of McCallum and Leonard to rely entirely on the grit of the narrative and the raw, rhythmic pocket of the soul.
By stripping away the ornament of chord progressions, this preview of the forthcoming album reveals the skyscraper of emotion that can be built on a single, unwavering foundation. It is cinematic, shadow-drenched, and deeply rooted in a heritage that understands that sometimes, to find the most expansive truth, you have to stay exactly where you are.
The track functions like a dark film unfolding in sound. Without the relief of a chord change, the listener is pulled into a relentless atmosphere. Here, the driving force is pure internal rhythm and structural restraint. The song breathes through micro-tensions, the way a vocal phrase leans against the beat, or the way Leonard’s guitar cuts through the air like light through a venetian blind.
By leaning into this structure, McCallum and Leonard capture the true spirit of the traditional odyssey. It is a journey that doesn't require a change of scenery to be profound, only a deeper look at the ground beneath your feet.
Behind the Bars: An Interview with Erin McCallum & Teddy Leonard
We reached out to Erin and Teddy to discuss the co-writing process behind this preview of the forthcoming album and the discipline required to master the "Infinite One."
Q. For Erin: The Weight of the Lyrics, You’ve often mentioned a 'lyrics-first' approach to songwriting. On a track with such a minimalist, one-chord foundation, did the words feel a greater responsibility to provide the song’s 'movement' and structure, since the harmony remained a constant?
Erin: I would say that a one-chord foundation is certainly a structure that allows for the words to be a primary focus. Much like the “minimalist” approach to the structure of “I Need A New Lover”, the vocal melody stays within a certain range that encourages the listener to focus on the words, and the subtle inflections that help put those words into context. Another factor in what makes the lyrics take on a greater responsibility in this song is that the rhythm of the vocal also mirrors the hypnotic approach to the structure; this is another aspect of the song’s minimalism that puts more focus on the words.”
Q. For Erin: The Psychology of Confinement "The single’s artwork is so striking—clinging to jail bars with a noir intensity. In the studio, did you find that the repetitive, hypnotic nature of the music helped you 'inhabit' that sense of being trapped, or did you have to fight against the rhythm to find your freedom as a vocalist?"
Erin: The short answer is; yes. If I deconstruct what really helps inject a feeling of urgency or angst to the intention of “I Need A New Lover”, I believe the structure creates parameters that someone may feel, if they can identify with the song’s message. As far as fighting against the rhythm goes, I would say that there’s a natural push and pull between the music and the vocal that leads the feel of the song. As a vocalist, embracing that hypnotic movement and letting it “hold” me in a certain place creates the tension that augments the vocal in “I Need A New Lover.
Q. For Teddy: The Architect of the Groove "As a guitarist known for your identification with the blues and your study of its heroes, what is the secret to keeping a single-chord groove 'breathing' for an entire track? How do you balance being the 'anchor' while still providing the cinematic texture this song demands?"
Teddy: I tried to make it as hypnotic as possible; it creates the mood for the listener, and it hopefully grabs them and puts them right in the middle of the song. The groove is so sparse that it allows the other players space to bounce off each other.
Q. For Teddy: The 'Influencer's Influence' "You’ve spoken about searching for the people who influenced your heroes. When crafting the sound for this single, were there specific 'minimalist' masters, perhaps from the Delta or West African traditions, that you drew upon to ensure the one-chord foundation felt like a skyscraper of sound rather than a limitation?"
Teddy: 'Smokestack Lightning’ and ‘Do The Do’ (by Howlin Wolf) are two of my favourite hypnoses.
Q. For Both: The 'Alone Together' Synergy "After years of performing your 'Alone Together' shows, your musical shorthand is well-documented. How much of the 'cinematic tension' in this track was pre-charted during the co-writing process, and how much was a result of that intuitive, split-second interaction that only comes from a long-term professional partnership?"
Erin & Teddy:
Teddy: You always pick the players for what they play, and you hope that the chemistry brings what you want - or more - to the song.
Erin: As a co-written song, I would say that “I Need A New Lover” is almost entirely built on the professional chemistry that Teddy and I have established through knowing each other’s strengths, preferences and musical tendencies. To Teddy’s point, we both know what we bring to the table, musically, and it makes for a solid foundation; it created the space to write the song in a completely collaborative way. It was also very easy to express our ideas and follow a natural path - there wasn’t much to hash out with respect to charting the song’s structure, because we were immediately on the same page with the vision of what it was supposed to do. When it came to the recording, I would say that those same characteristics helped bring the song’s intention to life - Steve Marriner (bass and harmonica) and Gary Craig (drums) applied their skillset, and applied it in ways that charts or structure would struggle to convey, and that’s the chemistry. When people are listening to the lyrics of “I Need A New Lover”, there’s a musical ‘call and response’ that’s happening with the instrumentation - that’s a result of unscripted chemistry happening in real time.
The Single will be released June 1st on all digital platforms.
The Sound Cafe Journal Verdict: In a digital age of overproduction, McCallum and Leonard find freedom in the singular. This isn't just a stellar introduction to a forthcoming album; it’s a cultural document that reinforces the importance of human-led storytelling. It is a bold, minimalist masterclass that proves the deepest stories are often told through the most honest foundations.
