Pittsburgh’s Complaints N’at Choir debuted Friday, and will perform nightly for the remainder of the Three Rivers Arts Festival.

The Choir, organized for the Arts Fest by artist and musician Christiane D. (pictured), is the local take on an international project to set complaints submitted by area residents to music and perform the songs in public.

Pittsburgh’s 10-minute tune is worth catching. As performed Friday by nine singers — including Christiane D., gospel singer Deryck Tines (doubling on keys) and Phat Man Dee — it was a jaunty, largely R&B-style number. Christiane D. accompanied the vocals with a sort of wry interpretive dance, like a majorette with an attitude.

The lyrics incorporated such timeless plaints as “Bus, how can you be so late and smelly?” and such universal ones as “People can’t say they’re sorry when they’re wrong.”

More cutting were grievances like “Lack of good jobs for black women and men” and “You got noticed as the most livable city and immediately got rid of everything that made you that way.”

The number of arts-centered complaints suggested the contributors of grievances included a fair number of artists. Passages in the song included a “Save the August Wilson Center” chant.

The Complaints N’at Choir performs at 6 p.m. nightly through Sunday at a different Downtown location each night.

Tonight, for instance, the choir takes over the portico of the City-County Building on Grant Street (the one with the Caligiuri statue).

Tomorrow, it’s in Katz Plaza; Wednesday, the Gateway Center Stage; Thursday, Market Square; and on Friday, the choir opens for Coronado and Curtis Harding on the Dollar Bank Main Stage, in Point State Park.
