Awesome post!
I just got home from work, opened up my Live on Ten Legs super deluxe vinyl boxset that arrived from England, and started listening to "Arms Aloft" (Joe Strummer cover). Then open my Google Chrome, go to 9:30 Club board, and see this thread. I love it.
I'm a huge Pearl Jam fan, so this is tough. But here's a try.
Also, are you sure some of those are studio released ("Everyday People," "Let My Love Open the Door," "Out Of My Mind," "RITFW")? Aren't those all live recordings only? Also, most of your list appeared on Lost Dogs. Not so elusive. Either way, I'm counting anything that wasn't on a studio album as a b-side.
I'm not including covers ("Crazy Mary" and all your honorable mentions) because there are at least a hundred of those.
1.) Breath
2.) Of the Earth
3.) Alone
4.) State of Love and Trust
5.) Foldback
6.) Strangest Tribe
7.) Long Road
8.) Hard to Imagine
9.) Hold On
10.) The Golden State

11.) Down

14.) Other Side
15.) Puzzles & Games
