Get dancing; there’s no excuse when this summer’s rockin’ ska-beated reggae-iffic “Unity Tour 2011” featuring the late ‘80s party bands 311 and Sublime with Rome roll into Bethel Woods on Monday evening, July 25 alongside special guests Deejay Soulman & Deejay Trichrome.

“What I Got” is the big hit from Sublime, back before it legally changed its name following the overdose death of its lead man/founder Brad Nowell and reunion replacement with Rome Ramirez a couple of years back. Now it’s up there in the top sphere of alt-Valhalla alongside the Red Hot Chili Peppers and Nirvana: other bands with past challenges and a lasting impact.

311, meanwhile, came up at the same time with less of a fast-ska sound, a bit more in its own scritchy-scratchy loud-guitar reggae groove. Also hitting it big in the mid-‘90s, 311 reached permanent cult status when it started celebrating its own “311” Day with bashes in New Orleans each March 11 – along with its annual Unity tours, which besides contemporaries also have featured some of reggae’s classic first-wave legends.

This is going to be one hot concert: loud and fun. Forget the kiddies (or the geezers) on this one. This is big-sound, professionally presented, perfectly pitched summerfest music. Think Sly’s power 40-some years after.

Showtime is at 6:30 p.m.; but remember, these dudes play long. It’ll be a full evening. For further information, including ticket pricing and directions, visit www.bethelwoodscenter.org.
