Featuring Christine Perfect--better known as the future Christine McVie of Fleetwood Mac--the British ensemble Chicken Shack offers up a solid set of blues-influenced rock on its 1968 initial outing.Personnel: Stan Webb (vocals, guitar); Christine McVie (vocals, keyboards); John Almond, Dick Heckstall-Smith (saxophone); Alan Ellis (trumpet); Dave Bidwell (drums).If one can overlook Stan Webb's hyperventilating vocal excesses (which ain't easy), this is a promising debut, especially noteworthy for Webb's Freddie King-inspired guitar sting and Christine Perfect's understated vocals (only two, unfortunately compared to Webb's six). Webb does justice to his mentor with two instrumentals, King's "San-Ho-Zay" and his own "Webbed Feet," and Perfect proves the ideal counterpart -- one of the few pianists paying homage to King's longtime collaborator Sonny Thompson. Nice spare sound, typical of Mike Vernon's Blue Horizon label.
