The Flaming Lips have done it again.  If you like "The Soft Bulletin" and 
"Yoshimi Battles The Pink Robots", you will dig their new CD "At War With 
The Mystics".  The first few tracks sound a bit like "Ween"; but, after that 
you have tons of Tron flute and a nice size helping of 3 Violins.  Killer 
tracks that jump right out at you are "The Sound Of Failure", "The Wizard 
Turns On...", and "Pompeii Am Gotterdammerung".
