With touring off the table during the pandemic, Grammy-winning singer/songwriter Jason Isbell and his band the 400 Unit have still kept their momentum: The group's latest album Reunions was released to physical indie record stores prior to digital services earlier this spring, they've played a string of socially-distanced outdoor shows, as well as continue to post archival performances via Bandcamp. On today's show, keyboardist Derry deBorja talks about all of the above, plus the musical influence of his older brother, his time as a member of Son Volt, how experimenting with a modular synth has changed how he views composition, and the 400 Unit's relationship with David Letterman.
