Mission Bay High School’s acclaimed eleven-piece student group The Preservationists will be going to New Orleans from April 17-20 to perform, learn and soak in the culture.  To raise money for the trip, the band is holding a fundraising concert at Tango Del Rey on March 26. Featuring pianist Sue Palmer alongside the Preservationists, the night will showcase the music of the Crescent City and selections from their most recent album, “New Orleans Preserves.” The trip will see the Preservationists perform on historic stages. “We have already set up shows at Preservation Hall, WWOZ New Orleans Radio and the New Orleans Jazz and Heritage Museum,” said the school’s musical director, JP Balmat. “We are also setting up special workshops/master classes with professional musicians in the city. We are hoping to give students the trip of a lifetime, learning traditional jazz from its birthplace.” • MBHS NEW ORLEANS FUNDRAISER: Wednesday, March 26 at TANGO DEL REY, 3567 Del Rey St. $10. 7 p.m. All ages. www.tangodelrey.com.
