Over the past several years the band has released several re-mastered albums and boxed sets. They are all excellent, I especially like DSOM box set with the 5.1 DVD... Included is a small sack of DSOM marbles... which might be a distributed back-up plan (disaster recovery?)
[Also re-released is Ummagumma with a pristine copy of "Several Species" uhhhh... what was I saying oh yeah, and if you have not yet listed to it, "The Endless River" final studio album is really quite good as background/contemplative mood floating content.]
