Blue Note and Verve have done it, now Impulse! has got hip DJs and electronica dudes to rework its back catalogue. The best of these are pretty leftfield – RZA mutilates Mingus, Prefuse 73 mangles Gabor Szabo and Telefon Tel Aviv turn Oliver Nelson’s ‘Stolen Moments’ into lush, cinematic psychedelia. There’s also a separate ‘Unmixed’ CD, where you can enjoy the Impulse! originals, including Archie Shepp’s chaotic Motown-in-space classic ‘Attica Blues’.
