Singer/songwriter Colleen Green is known for her sweetly gritty lo-fi pop sound. Influenced by bands like the Ramones, Sublime, and the Descendents, Green's early self-recorded tapes like 2010's Milo Goes to Compton and 2011's Cujo, were breezy punk- and new wave-inflected productions featuring Green's home-blended mix of vocals, guitars, keyboards, and simple drum-machine beats. She has retained her lighthearted spirit even as her music has grown more ambitious and musically organic, as on 2015's I Want to Grow Up and her 2021 sophisticated take on '90s alt-rock, Cool.

Born in 1984 in Dunstable, Massachusetts, Green spent time in Boston before moving to Oakland in 2009 with a handful of friends. Once there, they began playing live shows in their living room. However, after experiencing some health problems, Green moved to her brother's house in Los Angeles. It was during this period, armed with little more than a guitar and a drum machine, that she began writing and recording music at home. She quickly released a CD-R EP, 4 Loko 2 Kayla, and a cassette tape, Milo Goes to Compton, in 2010. The albums caught on among indie music bloggers, and Green signed with Hardly Art Records before the year was out. More EPs followed on the label in 2011 with Green One and Cujo. Also that year, Milo Goes to Compton was re-released as an LP on the Art Fag label. In 2013, she issued her sophomore full-length album, Sock It to Me, on Hardly Art.

In 2015, she returned with her third full-length album, I Want to Grow Up. Recorded in Nashville with JEFF the Brotherhood's Jake Orrall producing, the set showcased a more fleshed-out sound, marked by Orrall on guitar and Diarrhea Planet's Casey Weissbuch on drums. The following year, she issued a self-titled EP as a limited-edition cassette on the Infinity Cat label. The cassettes sold out quickly, and in 2018, the label re-released the material with additional bonus tracks as Casey's Tape/Harmontown Loops.

In the summer of 2019, Green fulfilled a longtime dream by covering blink-182's 1997 album Dude Ranch in its entirety. Cheekily titled Dude Ranch by blink-182 as Played by Colleen Green, the album found Green rearranging all the songs to be played only on bass guitar. When she set about the making of her third album, Green sought out Strokes producer Gordon Raphael and along with drummer Brendan Eder and hip-hop beat maker Aqua spent time in various studios in Los Angeles. Together they concocted a sound that hearkened back to the grunge pop sound of the '90s while putting Green's more mature spin on neo-slackerdom front and center. Cool was issued by Hardly Art in September 2021, by which time Green had left her adopted home of L.A. for her former home of Massachusetts. ~ Matt Collar, Rovi
