Whether it’s Julian Casablancas performing “I Wish it Was Christmas” with the Roots, Bright Eyes smashing the hell out of a trumpet onstage, or Ben Harper, Beck, and Billy Gibbons joining Will Ferrell and Conan for a rendition of “Free Bird,” late-night television affords us a wealth of entertaining performances (and just sheer entertainment) as far as musical guests go.

Ergo, each week, we round up every show’s scheduled performances and place them in a handy little list.
