Rock Docs is back after a lengthy hiatus — we've been saving up our discussion of the artist behind the second-worst-selling album in the history of Columbia Records, and the jam band world he helped pioneer.

Today's episode is about "Basically Frightened: The Musical Madness of Colonel Bruce Hampton," a 2012 documentary about the avant-garde artist behind the Aquarium Rescue Unit.

Our guest this week, author Mike Ayers, is the author of the excellent new oral history, "Sharing in the Groove: The Untold Story of the '90s Jam Band Explosion and the Scene that Followed."

Ayers is our tour guide not just through the career of Hampton and ARU, but Blues Traveler, Spin Doctors, Phish, the Dave Mathews Band, the Greyboy Allstars, Medeski Martin and Wood and even, at Andy's urging, ekoostik hookah.

Rock Docs is a Treble Media Podcast hosted by David Lizerbram & Andrew Keatts
