Though they possess the ever-marketable cute-girl lead singer and a large cult following, the Detroit Cobras have so far avoided the forked-tongue major-label demons slinking around D-town. But word is, they have finally put pinpricked finger to steaming contract with some major subsidiary imprint. And why not? This band's eight-year, two-album mission to revamp and rev up obscure '50s and '60s R&B nuggets has been an inspiration to the current garage-band glut. And the members are just old enough to be wise to the usual big-money exploitation. They're even ready to tackle some originals and have purportedly sought help from that wellspring of great garage-rock songwriting, Greg Oblivian (Oblivians, Reigning Sound). But once the booze starts flowing, all these careerist concerns shouldn't hamper the Cobras' always hot live show.
