(A quick note: the links below go to Lala.com - where you have to sign up to listen to the music, but once you do, you get to listen to the whole album.)
I got my copy of Easy Star's Lonely Hearts Dub Band in the mail today (thanks Amazon!). It's a "reggae re-imagining" of the Beatles’ Sgt. Pepper’s Lonely Hearts Club Band, and it's pretty decent (I'm a big fan of Easy Star's other reggae tributes). I've already listened to it a bunch of times, and a number of the songs have really been stuck in my head.
For a quick comparison (but only if you're familiar with Easy Star's other albums), Lonely Hearts Dub Band is not as good as Dub Side Of The Moon, but it's better than Radiodread.
Required listening for Radiodread: Paranoid Android, and Karma Police. Required listening for Lonely Hearts Dub Band: A Day in the Life. Required listening for Dub Side Of The Moon: The whole damn album. It's really good. It's an Xcoder's favorite in fact.
