hm... i still prefer BPE. Classical is good as a listening tool at home, but IMO many of the tunes sound weak for DJ use. they just lack muscle in the kickdrum department. i WILL admit that "Bust A Move" is one of the best trance tunes ever, and i have a love for "The Shen" and it's mad, crystalline synth builds. i also think CM has too many good moments that are bookended by fluff muzak (one of IM's tendencies, present yet again in the new album).
BPE is closer to progressive to me, and it is quite tasteful. a lot of "space" in the music, and a great, almost angry vibe in parts. if they had chucked "Roll Us A Giant" on the album (it fits, you know), it would have been insane.
waiting to read reactions to the new album.. should be interesting...
