The Pittsburgh Symphony Orchestra will be playing. The concert will be in Heinz Hall. But make no mistake: This concert is not about classical music.
"It is a full-up rock show," said Brent Havens, conductor and arranger of "The Music of Led Zeppelin," a score of the band's music that features a bass player, guitarist, drummer, lead singer and electric violinist -- and at least for tonight, the PSO.
Mr. Havens has transcribed for orchestra the catalogs of various bands and musicians, from Pink Floyd and the Doors to the Eagles and Whitney Houston. His group, Windborne Music, performed its Michael Jackson show in Pittsburgh in November.
The Led Zeppelin score was his first that married an orchestra to a rock band. He arranged it in 1995, for the Virginia Symphony Orchestra, when that orchestra's management was looking to cater to different audiences.
"I wasn't sure that would really appeal to Ledheads or Zedheads or whatever you want to call them," said Mr. Havens.
The idea took off, and now, Windborne performs eight shows, all of which Mr. Havens transcribed. Having composed for film, television and bands, he had experience working with orchestras and rock groups alike.
"The fact that I was familiar with all those sides of things made me a fairly good fit for this," he said.
When writing for rock bands and orchestras, he draws on certain techniques to make the orchestra and band blend as smoothly as possible.
"I use the electric violin as a bridge between the two," said Mr. Havens. As one example, the electric violinist takes on some of the catalogue's guitar solos.
The show will feature Brody Dolyniuk on vocals, replacing Randy Jackson (of Zebra), who is ill. Mr. Dolyniuk sings the arrangements of the Who, the Rolling Stones and Queen for Windborne Music.
