Dec. 16 Rad Kadillac Holiday Event w/ Somasphere, Mitch Gettman Band and SFS Waiting Room, 6212 Maple St. 9 p.m., FREE, radkadillac.com ’Tis the season to be rocking and giving! Rad Kadillac Productions is feeling festive this holiday season and has decided to give the Omaha community the gift of music. This Thursday, at The Waiting Room, the Rad Kad gang will stuffing your stocking with their annual free night of local music mayhem with up-and-comers Mitch Gettman Band and the hard riffing SFS from Lincoln. Headlining is Somasphere just off playing a holiday show to a capacity crowd at the Granada in Lawrence, Kan. In the spirit of giving, Rad Kad hopes the money you save from a free night of entertainment will inspire you to donate nonperishable food items and/or cash for the Omaha Food Bank. Be sure to wear your best obnoxious Christmas sweater because there will be a “family photo” at this event. As Rad Kad says, “Even if the weather outside is frightful, the vibes inside will be delightful!”
