Three artists who’ve each built their own kind of musical bridges alight in D.C. for a night at the Warner Theatre. Rachelle Ferrell branched out from jazz standards to apply her six-and-a-half octave range to other genres, from R&B to classical, and succeeded in maintaining the warmth and wisdom that distinguish her from many singers with similar technical talents. Keyboardist, composer, and producer George Duke has jazzed up recordings by Frank Zappa and rocked out with Billy Cobham and Stanley Clarke, and his recent entry in Columbia’s This Is Jazz series mixes his hot tub jazz of late with some Brazilian flavor and a bit of his old fusion funk. Rahsaan Patterson bridges not genres but coasts, he’s a New York-born L.A. resident, job descriptions, before turning recording star he co-wrote “Baby” from Brandy’s ’94 debut, and era, his eponymous debut last year was lauded for the “retro-soul” appeal of its modern R&B. At 7 p.m. & 10:30 p.m. at the Warner Theatre, 513 13th St. NW. $35. (202) 783-4000. (Daniel Searing)
