CBMC, a Philadelphia-based band led by Shari Heck, was active from 2013-2015. Heck wrote and recorded all the songs from her bedroom, focusing on themes of relationships, shyness, and introspection. Her lyrics, reminiscent of AIM away messages from the mid-2000s, blend angst with vulnerability, creating evocative portraits through gentle guitar strums and wordy, sentimental verses.

In a reflective message to fans, Heck shared her transition away from music-making, expressing gratitude for the emotional journey CBMC represented during her late teens and early twenties. Writing and recording in her off-campus apartment in Philly, Heck's openness and earnestness during this period are qualities she continues to admire in herself. As she moves forward, she acknowledges the passage of time and the lasting impact of CBMC on her life.
