Playwright Tyler Perry made his mark with African-American gospel stage plays. When one of his theatrical works came to the big screen, he wrote, starred in, and directed it. As the executive producer and major songwriting contributor for the DIARY OF A MAD BLACK WOMAN soundtrack, Perry was able to round up an A-list of R&B sirens. The result is a sweet-sounding cross-section of tunes, opening with India Arie's "Purify Me," which features a mix of acoustic guitar and gentle beats, and closing with Tamela Mann's roof-raising gospel workout "Take It to Jesus." In between, Natalie Cole tantalizes over the languid harmonies and seductive vibe of "I Wanna Love Again," and Angie Stone showcases her charismatic vocals over the slow rolling beats of "Different Direction." Cheryl "Pepsii" Riley makes the most impressive mark, shifting from the snappy jive of "I Wanna Swing" to an Oleta Adams-flavored interpretation of the Joan Osborne smash "One of Us." Riley also shines on a righteous reading of "Father Can You Hear Me," which features contributions by Tiffany Evans, Terrell Carter, and Tamela Mann.
