Are you a reggae ambassador or do you just play one on TV? We've got great news for you then, mon. Our pal Byron Shaw, the ever affable frontman of Judge Roughneck and the Byron Shaw Projex (and the Jonez, if you're old school), just informed us that the 3-D Lounge, Denver's only -- and, hell, for all we know, perhaps the country's only -- open reggae jam night is back. Every Monday night from 10 p.m. to close at the Open Tap (formerly Cafe Cero, two blocks north of Herman's Hideaway) all musicians, regardless of style or ability (really, Byron? Be careful what you ask for!), are invited to come down and jam out and get all irie on the music and stuff.
