Sugar on the Roof is Megan Orwig Reynolds on guitar and vocals, Jefferson Reynolds on banjo and trombone, Jen Krussow on upright bass, and Clancy Ward on fiddle and vocals. Blending American roots music from the 1930s and 1940s with their own originals, the quartet of sonic time travelers fiddles around at the foundations of American popular music. Their repertoire includes old-time fiddle tunes, country two-steps, Western swing classics and early jazz treasures. The honeyed harmonies merge with foot-stomping fiddle and banjo, with driving upright bass and swanky trombone to make it swing.
