by Stephen Thomas ErlewineFor Fabulous Thunderbirds fanatics, or anyone longing for the raw gutbucket blues-rock of their early recordings, Different Tacos is something of a godsend. Essentially, the disc is a rarities collection, boasting nine outtakes from their first four studio albums, a couple of live cuts from various U.K. tours, and a nearly complete set from an Austin club gig in the late '70s. Each track is straightforward, take-no-prisoners Texas blues, played with astonishing fervor and grit. There are alternate takes and live versions of familiar T-Birds items, plus covers and songs that were reworked or abandoned for the original albums. Certainly, the nature of this live and rarities set makes Different Tacos primarily of interest to hardcore fans, but those fans will find it a most welcome addition to their Thunderbirds collection.
