The solo project of multi-instrumentalist, horn arranger, and yMusic trumpeter CJ Camerieri, CARM's reflective, atmospheric tracks rely on acoustic instruments, including brass, for their framework. Additional components, however, sometimes include things like samples, programmed drums, and electronics as well as traditional rock instruments. Justin Vernon was among the guest vocalists on the frequent Bon Iver collaborator's 2021 debut album, CARM.

New Jersey native Carmen Jonathan Camerieri, better known as CJ Camerieri, found work recording with the likes of Sufjan Stevens, the National, and Rufus Wainwright by the mid- to late 2000s. In 2008, he co-founded the chamber sextet yMusic, an ensemble that went on to collaborate widely in the indie music sector while releasing albums of their own instrumental compositions. Over the next decade or so, in addition to his work with yMusic, Camerieri contributed to Bon Iver's Grammy-winning eponymous album (2011), Paul Simon's Stranger to Stranger (2016), and Taylor Swift's Evermore (2020), just to name few.

In 2021, Camerieri presented his first solo album, using the moniker CARM. Co-produced by Camerieri and Ryan Olson, the self-titled set arrived on the 37d03d label that January. Consisting of varied indie-oriented instrumentals and some songs, its guests included Justin Vernon, Sufjan Stevens, and Mouse on Mars. ~ Marcy Donelson, Rovi
