"Hallelujah" includes literally one great blues song after another in an impressively eclectic set. "Cookbook" is a collection of Canned Heat's finest recordings up to that point, essentially a 'greatest hits' from the period. It features the classic Canned Heat lineup of Bob "The Bear" Hite, Al "Blind Owl" Wilson, Henry Vestine on guitar, Bob Cook on drums and bassist Larry Taylor.
