Gabriel Douglas has built his reputation on the churning, heavy-thumping blues rock of the 4onthefloor, whose sound is defined as much by his wild man warrior-bellow vocals as it is by the steady pulse of the four members’ synchronous bass-drum thuds—but a delve into the corners of his catalog reveals an artist with a startling breadth of interests.

The man keeps busy, holding down gigs in several stylistically distinct groups while regularly performing and recording solo. Below is a concise guide to help you get a handle on Gabe’s many moods and many bands. You can use this guide to bone up before the May 26 release of the 4onthefloor’s new album, All In, or to hunt down some deep cuts to request at their upcoming headlining show at First Avenue on May 22 with American Aquarium and Dan Mariska.
