Revelator is the sheer size of the band pictured on the front of the CD. We're used to rock trios, quartets, and quintets. We've seen some bands grow beyond that- The E Street Band, for instance. An 11-piece rock band? Where's the template for that?
Derek Trucks and Susan Tedeschi said the majority of these songs began as spare, acoustic sketches that evolved when presented to the band in the studio. From that perspective, the material did grow in scope and complexity but don't let the largess of the band or the Trucks' work with his own Derek Trucks Band or the Allman Brother Band lead you down the wrong path – get the wrong idea. This is a song-oriented record, not a collection of loose or extended jams.
I had trouble warming up to Derek Trucks Band and listening to Revelator, now I know why. As technically gifted and evocative as Trucks' playing is, there was something missing on DTB albums. He needed the right singer and the right songs, and he's found them.
