PINK MOUNTAINTOPS VS. FEDERATION X - TO ROCK OR GET ROCKED

Toss up for tonight with so much going on this evening.  Hoping the sun with stay for the day, shining brightly for the onslaught of rockin' roll that will take over Portland this evening.  Torn between these two events:

ROCK! Canadia's Stephen McBean of Black Mountain gets together with friends and members of BM, to bring you his brand of psychedelic folk rock ala sex love!  Pink Mountaintops play Bunk Bar this evening!

OR GET ROCKED!  FEDERATION X plays Rotture tonight along with Danava & Leaders.  This is definitely a rock show not to miss.  FX originally hails from the northern territories of Bellingham, WA., not sure if they are still calling that home, but pride of Washington they are.
