New Orleans trumpet and sax player and educator Brian Graber has reached out to the New Orleans music community because his wife, Carin, is being treated for brain cancer at M.D. Anderson Hospital in Houston. Doctors have suggested she have a therapy known as a proton blast, but her health insurance won’t cover it. Graber has played with George Porter Jr. and the Runnin’ Pardners and John Mahoney’s Big Band, both of which will play this fundraiser for her treatment. Tab Benoit, Bonerama, The Boogiemen, Dave Ferrato and Tchoupazine, Tom Fitzpatrick Band, Pink Magnolias, Dave Jordan Band, and more will also will perform.

Rock band The Polyphonic Spree made its name by playing grand, sweeping songs with a 22-person band including an 11-voice choir. Initially, the group presented itself as a cult, and while that aspect has been played down in recent years there’s still a strong undercurrent of positivity in its words and sound. Last year’s “Yes It’s True” dialed back some of the bigness without losing the Spree’s eccentric, melodic charms.
