The problem with most postmodern pastiches (aside from the soulless chill of their irony) is the practitioners' often cursory knowledge of the cut-and-pasted genres. Geoff Muldaur has been seamlessly combining musical styles for decades. From 1963 with the Jim Kweskin Jug Band, through his duet records with then wife Maria, to his Better Days tenure and later solo work, Muldaur has lent his distinctive, bluesy, soul-drenched vibrato to tunes by everyone from Blind Lemon Jefferson to Jimmie Rodgers to Hoagy Carmichael. The man thinks nothing of combining violin, bassoon, clarinet, and French horn into Ellingtonian textures for a cowboy waltz ("Prairie Lullaby") or putting a string section and an accordion on a Charley Patton tune ("Some of These Days"). All this is done in an irony-free zone of innocent enthusiasm combined with a thorough knowledge of the song's roots.
