Eclectic, Independent, & Electric

Immutable is a Boston-based vocal band that performs an eclectic mix of R&B, 90s, and current pop tunes, as well as a few originals. We've gone by a few different names over the years, but one thing is immutable--our love of music!

Our repertoire includes songs by Michael Jackson, The Beatles, Mariah Carey, Ray Charles, Sara Bareilles, Matthew Sweet, Gin Blossoms, Scissor Sisters, Paul Simon, Jackie Wilson, Hall and Oates, and many others.
