This is perhaps the hardest vote for me in Round 1. Both are on the Yella Piss top 10 albums of all time. Rubber Soul for me - with about half of its songs - was the Beatles finest work. It's the album the birthed album oriented, classic rock. Alas, it's still got about 4 to 5 weak cuts of filler. Who's Next on the other hand plays as well front to back as anything ever recorded. 7:30 in on "Won't Get Fooled Again" is IMHO the greatest moment in rock history.
