Cairo Fred at Blues Alley: Cairo Fred collects descriptions and genre labels the way some people collect passport visa stamps. Its music has been called pop, alt-rock, Americana, adult contemporary and pop-jazz, among others. In the view of the D.C. sextet, who released their album “Freedom Street” earlier this year, all those descriptors are valid. “We are many things. A disparate bunch of things put together,” says Desson Thomson, the band’s lead vocalist and (with guitarist/pianist Bradford Heck) songwriter. “Freedom Street” runs the gamut from “Raincoat,” a jazzy heartbreak ballad that was the first song Thomson and Heck ever wrote together, to “Everything” — which the band thinks might be the world’s first track to combine hip-hop influences with pedal steel. 8 p.m. and 10 p.m. $35.
