I saw We Jam Econo

but I haven't seen the other one.
On wikipedia say it focuses on these bands:
Black Flag (from Hermosa Beach/Los Angeles, California)
Minutemen (from San Pedro/Los Angeles, California)
Mission of Burma (from Boston, Massachusetts)
Minor Threat (from Washington, D.C.)
Hüsker Dü (from Minneapolis - Saint Paul, Minnesota)
The Replacements (from Minneapolis - Saint Paul, Minnesota)
Sonic Youth (from New York City, New York)
Butthole Surfers (from San Antonio, Texas)
Big Black (from Evanston/Chicago, Illinois)
Dinosaur Jr. (from Amherst, Massachusetts)
Fugazi (from Washington, D.C.)
Mudhoney (from Seattle, Washington)
Beat Happening (from Olympia, Washington)

I love most of those. I'll check it out, Greggo.
