He turned me on to seek out some new music in the form of Porcupine Tree in explaining surround sound CDs one day on Home Theater Geeks podcast. Intensely great stuff.
I see you've now joined the throng of fans around this great band (which has now disbanded). I don't know how exposed you might be to the current "prog rock" scene, but if you like PT I can easily recommend several relatively new bands that you might also enjoy.
BTW, there are tons of prog fans and discussion over at
www.progressiveears.org where you will likely discover much great new music.
Here's a few you might want to check out ...
Steve Wilson - The Raven That Refused to Sing, Grace For Drowning (new solo albums from PT's guiding light)
Haken - Aquarios, Visions, Mountain (all are great)
Big Big Train - The Underfall Yard
Anathema - Weather Systems, Hindsight
Katatonia - Dethroned & Uncrowned, Dead End Kings
The Pineapple Thief - All The Wars
OSI - Blood, Free, Fire Make Thunder
RPWL - Beyond Man and Time
Enjoy,
Bob
