No other solo American guitarist this century has impacted that fecund scene quite like William Tyler. After crucial stints in Silver Jews and Lambchop, this adopted son of Nashville emerged at the dawn of the last decade with a string of inquisitive albums that paired the measure of his country rearing and classical enthusiasm with his ardor for post-modern experimentation, field recordings and static drifts folded beneath exquisite melodies. Tyler dug Chet Atkins and Gavin Bryars, electroacoustic abstraction and endless boogie. His productive little enclave of instrumental music has increasingly followed such catholic tastes, not only ushering new sounds and textures into the form but also critical new voices and perspectives.
