It's a big episode but it could have been so much bigger and probably should have been split in half:
25th Anniversary of Regulate...G Funk Era by Warren G
25th Anniversary of Welcome to Sky Valley by Kyuss
25th Anniversary of Yank Crime by Drive Like Jehu
20th Anniversary of Enema of the State by Blink 182
20th Anniversary of Californication by Red Hot Chili Peppers
20th Anniversary of Astro Lounge by Smash Mouth
20th Anniversary of Ágætis byrjun by Sigur Ros
20th Anniversary of Supernatural by Santana
20th Anniversary of The White Stripes
20th Anniversary of The Beta Band
20th Anniversary of Significant Other by Limp Bizkit
20th Anniversary of Slipknot
The crazy thing is there could have been at least 3 more records.
