Generations of roots-revering rock 'n' rollers have bowed down to Doug Sahm and his Sir Douglas Quintet. They stirred Tex-Mex and country with garage, British Invasion and R&B flavors to make a delectable stew that collectors have been feasting on ever since. Here are the enduring, adventurous singles they recorded after moving from Texas to San Francisco: The 1969 hits Mendocino and Dynamite Woman plus at the Crossroads; Nuevo Laredo; Texas Me; Michoacan ; Sahm's heartfelt take on Freddy Fender's Wasted Days, Wasted Nights 22 Mercury/Smash/Philips A-sides, rare B-sides and solo Sahm gems on CD or double-vinyl!
