It's not an exaggeration to say this is the biggest moment yet for Portland's ascendant rap scene. Local musicians have appeared on late-night television before—Typhoon and Sallie Ford played Letterman in the same week back in 2011—but you have to dig pretty deep to find the last time a Portland hip-hop act was showcased on a national stage. New jack swingers the U-Krew rocked Soul Train back in the '80s, and Yung Mil was on BET a few years ago, but this is obviously on a whole other level.
