Pearl jam is my favorite band also, and Riot act is probably also my favorite album of theirs.
If you like Pearl jam, I'd recommend my favorite album of all times: Soundgarden's Superunknown.

- "Hitomi ni utsuru keshiki" - Luminous, Mayuko
- "Strange fruit" - Nina Simone
- "Boulevard of broken dreams" - Maiya Sykes, Postmodern jukebox
- "Mr. Rattlebone" - Matt Maeson
- "Stubborn beast" - Bear's den
- "Blue eyes" - Springbok nude girls
- "Farsi prayer" - Lisbeth Scott
- "Hey ma durga" - Krishna Das, Baird Hersey, Prana
- "Bright morning stars" - The wailin' Jennys
