Several volumes in this French, promo-only series should be snapped up whenever they're seen. For fans of cutting-edge dance music and left-of-center indie, they serve a function similar to that of the samplers that come with CMJ magazine, providing up-to-date selections of what keen club DJs spin. The value of the average volume in the series is considerably high since many of the tracks are available on vinyl only. The 22nd Trax Sampler includes Breakbeat Era's "Bulletproof," Death in Vegas' "Death Threat," Jay Denham's "Radio," Terranova's "Just Enough (Rough Cut Mix)," and Peace Orchestra's "Who I Am." Decent across the board, but not essential.
