ROCK 'N' ROAR
7 p.m., Civitan Amphitheater, Little Rock Zoo. $8.
Last time I wrote about Rock 'n' Roar, for the concert series kick-off last month, I made a big deal about it being spring and the birds chirping and short sleeves and all that, but as it turned out, I jumped the gun just a tad. Now, thanks to the crystal ball that is weather.com, I can tell you that it's likely to be somewhere between long sleeve T-shirt and light jacket weather on Saturday — not coincidentally, a near perfect range to watch a concert outside at the zoo. The formula remains intact: the comfortable and sheltered Civitan Amphitheater, authentic Mexican food from Mendoza's taco truck, two outstanding local musical groups and lions, tigers and bears. If you're lucky, the zoo will turn on its carousel for end-of-the-night rides like it did last time. On the bill: Runaway Planet and Chris Denny. The Planet has long been Central Arkansas's most active and beloved bluegrass act, while Denny's picked up steam in the last few years with his preternaturally strange and affecting voice, riding his talent to a national record contract and major label courtship.
