The acoustic blues renaissance is mostly about solo or very small ensembles.  The Bluff City Backsliders, though, are a whole different animal.  This is an acoustic blues orchestra.

Besides bass, drums, and guitars, the group also includes fiddle and mandolin played by two different people.  Honky-tonk piano, trombone and lap-steel guitar are also full-time chairs in this eight-member group.

Singer Jason Freeman handles all the vocals except on St. James Infirmary.  Backing vocals are used only rarely.  Happily, Freeman has a distinctive, rockabilly-ish style that works well on the material.

While their name suggests a jug band, as does their Memphis locale, the band doesn't sound like a jug band.  There is no harmonica, no kazoo, and no jug; they have a full drum kit, and they favor slow tempos.

The Bluff City Backsliders play American roots music, on a blues base (Howlin' Wolf, Bo Carter, Charley Patton, Willie McTell, John Estes are among the song composers) but with strong touches of old-time country and New Orleans Jazz.  Whatever it is, it's tight like that, as the song says.  A great album, accessible to moderns yet deeply traditional.
