The Louisiana State Museum in partnership with the Ponderosa Stomp presents "Cocktails and Conversations with the Unsung Heroes of Rock 'n' Roll" on the second Friday of each month. The inaugural event tonight features an interview with legendary arranger and composer Harold Battiste by WWOZ DJ and documentarian (and Gambit contributor) David Kunian. Battiste founded the record label A.F.O. (All For One), and he arranged Sam Cooke's "You Send Me," Sonny and Cher's "I Got You Babe," Joe Jones' "You Talk Too Much," and Lee Dorsey's "Ya Ya." He also produced Dr. John's early albums (Gris Gris, Babylon and Gumbo). He also was instrumental in the Jazz Studies program at UNO. Admission to the event (5:30 p.m.-8 p.m.) is free, and the Ponderosa Stomp curated "Secret History of Rock 'n' Roll" is open. There is a cash bar.
