by Rick AndersonBy the mid-'90s, Material was simply another word for Bill Laswell, so as Laswell's fascination with ambient mysticism grew, so did Material's tendencies in that direction. After 1991's dark and reggae-inflected The Third Power, Hallucination Engine's long, spacy jams aren't exactly a dramatic departure, but the combination of Wayne Shorter and various North African elements is certainly interesting. In fact, the array of guest musicians is more diverse than ever: Trilok Gurtu, Jonas Hellborg, Zakir Hussain, Bootsy Collins -- the list goes on and on and even includes William Burroughs (who intones a hilarious list of "Words of Advice" over a churning mid-tempo funk groove). In his ambient mode, Laswell has been accused of turning too little music into too much track length, and there's some justice to those criticisms; here, "Black Light" and the unbelievably well-named "Eternal Drift" both plod along for far too long with far too little development. But that William Burroughs track kicks in just as you're about to fall asleep, and it's followed immediately by a very funky and very jazzy remix of "Cucumber Slumber." "The Hidden Garden/Naima" proposes an interesting juxtaposition of Arabic pop song and modal jazz, with dramatic and beautiful results, while "Shadows of Paradise" brings the album to a close with a gentle whimper, not a bang.
