The annual Tunes & Blooms concert series at the Cincinnati Zoo kicks off today. Despite the late-coming spring, the weekly series — which showcases two local musical acts at each event — is in honor of the blooming flowers of the Zoo's Botanical Gardens. At least the snow is gone … (If you're going purely for the flowers, the Zoo's website says, "Due to unusually cool temperatures, our horticulture experts don't expect our tulips to be in bloom until mid April.")The free concerts go down every Thursday in April and run 6 p.m. - 8:30 p.m. Admission to the Zoo is free after 5 p.m. If you park in the Zoo lot, it'll cost you $8.Today sees the return of Bluegrass supergroup the Comet Bluegrass All-Stars and Americana supergroup Magnolia Mountain.Here is the rest of the month's lineup:April 11: Jake Speed and the Freddies/The TurkeysApril 18: Shiny & the Spoon/Shiny Old SoulApril 25: The Ark Band/The Cliftones
