The Hot 8 Brass Band's fifth album, On the Spot, is inspired by its playing in second-line parades and on the streets. Sousaphonist and bandleader Bennie Pete attributes the title to the moments when the band creates new music spontaneously, especially while providing hours of music for a second-line parade. Most of the songs are marked by the loose, celebratory vibe of a parade or club gig, particularly the first four original tunes. Pete's sousaphone drives the band as horns scream and the snare drum rattles on "8 Kickin' It Live," "Bottom of the Bucket" and the title track. The Hot 8 has incorporated hip-hop, funk and popular songs into its repertoire, and the album includes extended versions of Stevie Wonder's "That Girl" and Sade's "Sweetest Taboo." Clarinetist Dr. Michael White sits in on the band's nod to tradition, a cover of "St. James Infirmary," and percussionist Alfred "Uganda" Roberts also appears on a track. The album is intended to honor the families of lost band members Demond Dorsey, Jacob Johnson, Dinerral Shavers and Joseph "Shotgun Joe" Williams. The album officially was released March 31, but after tours of the West Coast, France and the U.K., the band is home to celebrate its release at the House of Blues. Keedy Black and DJ Soul Sister open. Tickets $15.
