It's a bit long, but I'm glad they went all out. Enough material on it to be very fascinating. It's almost like some weird audio-documentary at times. A lot of the songs are pretty damn catchy as well after a bunch of listens.
I know Decals is said to be better, and other Beefheart I haven't heard yet, but I haven't been able to get into Decals as much. The 2 guitarists interplaying with each other is one of my favorite things and on Decal there's only 1 guitarist if I remember right. I'm sure the melodies are better, i dunno.
