The new The Mars Volta album (not Mars Volta, who are totally different) is easily the best prog album I have heard in years, it is goddamn astounding. I would compare it more to Yes than anyone else... maybe some King Crimson here and there. But it is very fresh, energetic, and new sounding... which seperates it from most prog. There are a lot of very intense instrumental moments with godlike bass from Flea of RCHP fame, and there are soaring falsetto vocals from Cedric that sound actually quite good instead of the typical balls-in-a-vice sound of Geoff Tate, James Labrie, etc. Pretty long songs, including one 12+ minute song entitled Cicatriz ESP. It's not out until June 24th, but download some mp3s... you won't be disappointed. One of the best songs, Drunkship of Lanterns, is available as a free mp3... just google it and you will find it easily.
