The "Reggae Riddim Revival" rides into Last Concert Cafe Friday with D.R.U.M., Bigga Staar, Zin and DJ Meshak, plus live painting and dancers. Before 9:30 p.m., cover is only $5 if you bring a hand drum. In case you were wondering, there will be a drum circle.

In one of the oddest bookings we've seen in a while - although to be fair, the show was originally at House of Blues - Jamaican legends the Skatalites play Mango's Friday. Those of you thinking that this couldn't possibly be true, it is listed on the band's Web site. Expect a full house; as of Thursday night, more than 230 people had RSVP'd on Facebook, and Mango's is not a big place.

If for some reason Mango's is a mob scene -- and Rocks Off is not saying anything, but we are the tiniest bit skeptical -- you could always walk across the street to Classic Numbers. If you go, request some Echo & the Bunnymen for us; Rocks Off has had "Lips Like Sugar" in our heads for weeks. Or you could wait until Saturday, when one of the highlights of the club's calendar, Underworld's Gothic Beauty Pageant, celebrates its 13th year. Your DJs are vv James and Genesis, and MCs are Kevin de Vil and Ryan Rotten. $10.

If you have children, Rocks Off does not envy you, but you might want to consider the Houston Children's Festival, which claims to be the largest festival of its kind in the nation with a projected attendance in the 50,000 range. (Jesus Christ, that's a lot of kids.) Friend of Rocks Off Leah White and her band the Magic Mirrors perform at 10:30 a.m. Saturday on the Kids Directory Stage. Tickets are $10 at the gate or $8 in advance.

Benjamin Wesley, whose new album Think/Thoughts is probably going to end up on a bunch of local critics' best-of lists (this one likes it too), plays a free Cactus Music in-store at 5 p.m. Saturday. Austin rockers Electric Touch, work the early shift at 1 p.m. More on them a little later today.

Houston's Somewhere Between Here and There, El Bodo and In Altum compete for a trip to London in Hard Rock Cafe 9 p.m. Sunday at the music 'n' memorabilia franchise's Bayou Place location. Winner gets a chance to compete in the "Hard Rock Calling 2012" in London's Hyde Park. Good luck, guys.
