Ah, the halcyon days of rave-those heady moments of dancefloor epiphany, stolen away in the setting of a dingy warehouse with the morning sun filtering in through skylights and the infectious sound of a TB-303 acid line writhing its way out of the speakers. Sound familiar? If so, you’ll appreciate Ceephax’s homage to that genre of dance music known simply as “acid”-it’s all here, everything from the jittering chirp of the 303 to the taut kick drum to the warbling synth melodies. Ceephax’s album itself gears down the tempo and gets decidedly more cerebral, whereas the bonus CD favors brain-curdling acid techno jams.
