Hi,
The band with the most diverse catalogue in my collection would be Amon Duul to Amon Duul 2.
Stage 1. Coming from a commune, where everyone got stoned several days a week for a music-in and then orgy, for sure, someone taped some of these sessions and released them. When you hear them, they are ... not sure any of us will ever call that music ... it's just folks having some fun, whining, whirling, adding some singing, and some different things, that are not likely to be coreographed.
Stage 2. Some folks want to leave and go further with the music. Result Amon Duul 2 and "Phallus Dei". The first piece is a long piece, like the previous improvisations, and it starts out tripping and becomes a party ... and it is almost the same thing as the previous trips, except more focused to make a point ... that all this early stuff was just an excuse to get laid! ... but they were too stoned to know the difference.
Stage 3. Massive improvisational era. "Yeti" is the very best guitar solo/lead I have ever had the pleasure to enjoy ... it's non-stop, unafraid ... and confident, and capable ... and it does not repeat itself. "Dance of the Lemmings" is also totally out there, with the most psychedelic lyrics around.
Stage 4. Music gets better focused and killed. "Wolf City" is one of the best rock albums ever done. The follow up was almost a copy of the previous album, but after the anthem about the end of the old days and the dope, the band went to just a few commercial pieces of music. "Vive La Trance" does have this anthem (mentioned), and another piece that is ... one of the most memorable and vicious attacks ever, on anything ... check out the brief lyrics on "Mozambique" and then the acid rock assault after it ... and the very subtle bittie after it ... "unite and fight".
Stage 5. Very commercial sounding ... but "Hijack" made a point of flipping a finger to that thing, and do something else. The lyrics are still biting and pointed. "Explode Like a Star" ... is really strong ... "please make up your mind before I make it up for you ... "and is about drugs. It ends with a satirical song about putting the devil on TV ... which The Firesign Theater had already done, but not in song.
MAGMA --- is ... an acquired taste and not for everyone. The mix of what appears to be jazz, Carl Orff and Rock, and whatever else you want to call those vocals and its own language, is strange, and nice at the same time, but they have done this for 40 some years, and some of their catalogue is absolutely insane and amazing at the same time. AND, it was one of the most satisfying concerts I have ever seen in my life ... everyone here on this board can do the ABC's ... I wanna see ons of them step right up in the middle of this ... I don't think it is going to happen ... and the music folks create here is mostly the same as all other music, and not as vastly different as this one can be.
Amon Duul still takes the cake!
