First time listening to The Mars Volta and it's amazing! I haven't listened to something that immediatly clicked so well in a long time, so good.
So cool you like it. "Zed & Two Naughts" & "Aegis" are two of my favourite songs by the band, and "The Malkin Jewel" has this creepy atmosphere which I've always liked from them.
Awesome man, what album should I listen to next?
Yeah, pretty much what Train_of_Naught said.
Noctourniquet (as I recall) has much more keyboard/electronic sounds than the 3 albums before it, so if you like that vibe,
De-loused In The Comatorium is a good place to go. It also features Flea on bass in almost all of the record
