A venture to this state park is on the must-do list for many, the park being the only spot in North America where you can dig for diamonds and other gemstones and keep your finds.
8 p.m., Peabody RiverTop Party. $5.
They might not draw the biggest crowd — that feat almost surely will be accomplished by '80s cover band Venus Mission — but the Peabody doesn't have a bigger name on the schedule for this year's RiverTop Party concert series. Long a heavyweight on Southern stages, New Orleans act Cowboy Mouth barrels into town in support of their latest album, “Voodoo Shoppe.” Recorded pre- and post-Katrina, the album captures the party rockers in poppy kiss-off mode (in “Joe Strummer,” lead singer Fred LeBlanc is dumping a girl because she doesn't know who the Clash front man is) and in a more reflective spirit (“Home” considers post-Katrina devastation). Even though LeBlanc is the sole original member, the band's punchy rock sounds mostly unchanged. “Jenny Says,” the 1996 song that might be the group's biggest hit, sounds right at home next to Cowboy Mouth's newest single, “Kelly Ripa,” which, perhaps predictably, includes lines like “a mommy, with a body of a strippa.”
