allmusic.com: One of the longest-lived underground rock groups (if not the longest-lived), the Red Krayola lasted through the birth pangs of psychedelia past the death throes of post-punk. The one constant in its ever-shifting lineup was principal singer/songwriter/visionary Mayo Thompson, who seemed as concerned with deconstructing the language of "rock" music as with actually expressing himself within it. That made Red Krayola's catalog challenging, often difficult listening. Its saving grace was the quirky charm of Thompson's songs and vocals, with a whimsical humor and open-mindedness rather atypical of avant-rock.
