“Lifetime,” a self-produced single featuring backing vocals by McGuire's former piano student Paige Pfleger, was released in 2017. With no label or promotion, the ethereal song caught the attention of KCRW's Jason Bentley, and it charted up at #6 on his show Morning Becomes Eclectic in early 2018.
Starting in April of 2018, Straight White Teeth will release a loose collection of singles one and two tracks at a time under the name Physical Truth. From danceable synth-driven efforts to quiet folk-inspired ballads, this disparate collection of songs was written during a year-long period that McGuire spent traveling across North America with his partner, artist and collaborator Ella Trujillo. The songs featured on Physical Truth were written in locations like New Orleans, Toronto, the upper peninsula of Michigan and the Oregon coast after McGuire recovered from a serious biking accident he sustained while living in Philadelphia.
