Particles and Waves is like tip-toeing around the edges of dream. It's thin, electronicy, slightly insubstantial and a real joy to listen to. I never really rated Future Songs, don't know why, it just didn't really appeal. The other albums though are fantastic, however if you're expecting something along the lines of Wings of Joy or Forever with the thumping bass and driving melodies then forget it. Particles and Waves is not like that at all. There's a dynamism in the other albums that's missing from Particles, but not in a bad way. Kind of like taking the middle out of a merringue, leaving a very thin shell then putting it in the sun. It's all melty and dreamy. A truly excellent album from one of the most intersting bands around.
