Constant Sorrow takes a more studied overview of the whole blues scene from its roots in the 1920s and 1930s, through the growth between 1940 and 1950 to the flowering of the music and its mainstream acceptance in the late 1950s. Charmingly known as "Old Time Music" or just "Old Timey", the music of this compilation features notable contributions from Uncle Dave Macon, Mainer's Mountaineers, The Delmore Brothers, The Carlisle Brothers, Roy Hall's Blue Ridge Entertainers, Jimmie Skinner, The Lonesome Pine Fiddlers, Jim Eanes & The Shenandoah Valley Boys, Mac Wiseman, Joe Maphis and Jimmy Martin.
