Ashra- PTree has been to the TROC in Philly twice, this year and 2004, where they opened for Opeth. Both times the sound has been horrible, not sure if it's the band's or the venue's PA system at fault. 2001 at the TLA, 2002 at the TLA and 2003 at the Tower had stupendous sound quality, try to catch them somewhere other than the Troc, they'll be doing a fall tour this year.
Stupid Dream is their most acessable (and my personal favorite) release, but it's currently OOP, should be re-released in the near future.
