The Praxis cd Transmutation (Mutatis Mutandis) is the one with Buckethead, Brain, Baby Bam (from the Jungle Brothers), Bernie Worrell and Bootsy Collins. By and far, it's a solid album, and the most listener-friendly out of most of the Praxis albums. And those 5 guys on one cd-BRILLIANT casting job.
If you take all of that music that Laswell did on the Axiom label, it's some really interesting stuff. Yes, some of it is really avant garde crap, but there's some gems in there. I reveled in listening to some of the mid-90's Material stuff, the compiliations and such. But beware, some of the other Laswell produced and played stuff is WAAAAY out there.
If you ask me, for what Axl says about taking the sound to another level, I would figure he listened to a lot of this Laswell stuff and was greatly influenced by it (and NIN and other Industrial stuff). But from hearing Silk Worms and Madagascar, I wouldn't be surprised if Axl proclaimed a great liking and influence from Laswell. Makes sense to me for his recruiting of Buckethead and Brain.
