Composer Hayden Wayne is an example of a new breed of mavericks whose formative experiences are rooted in the 60s and who now embrace music as a celebration of diversity and ethnic pride. Born to a musical showbiz family and largely self-taught, Wayne started out as a rock keyboardist–touring with Sly Stone, the Fifth Dimension, and Gladys Knight and the Pips–and also wrote commercial jingles and scored for film. Yet like many musicians in the pop field, such as the Police’s Stewart Copeland, he yearns for respect as a classical composer, tackling “serious” subjects and forging a blend of idioms that he believes is unique. His compositions in this vein bear titles such as Funk (Symphony no. 4) and Rock-n-Roll (Piano Concerto no. 1). A hobby of his is studying tomes on orchestration by the likes of Rimsky-Korsakov. Not surprisingly, his Symphony no. 5 (aka Africa), whose third movement will be premiered locally in this program, has the ample scope and lush sound of a late-19th-century tone poem. Inspired by the rhythms of African tribal rites, this sprawling work is evocative yet luridly bombastic, a heavy-metal sensibility driving a montage of colorful tableaux. Also on the Sinfonietta’s typically eclectic program is Ballad for Symphony Orchestra and Jazz Trio by pianist patriarch Ellis Marsalis, whose trio will also perform a medley of his arrangements of Duke Ellington tunes. More traditional fare is represented by Prokofiev’s Symphony no. 1 and Vivaldi’s Concerto Grosso in A. Paul Freeman conducts. Sunday, 2:30 PM, Rosary College, 7900 W. Division, River Forest. Monday, 7:30 PM, Orchestra Hall, 220 S. Michigan. 857-1062. TED SHEN
