They've just released a complete 2 hour live performance from the Fear of a Blank Planet tour, as a high-quality mp3 download.
These guys *rock* live. £8 for a 2-hour set.
AND! All Porcupine Tree's profits from the sale of the Atlanta download will go directly to the Mick Karn Appeal. Burning Shed's profits will go to Macmillan Cancer Support.
If you like post-progressive rock with lots of fabulously complicated drumming, give it a try.
