Rock music can be a form of therapy. That's the thinking behind tonight's Rock Against Dementia, a benefit concert that takes place from 6 to 8 p.m. at Music Box Supper Club. There will be a silent auction and a showing of clips from the movie Alive Inside. Performers include Ain't Just Whistlin' Dixie, Dead Ahead, Big Ship and the Outlaws I & I (former members of First Light). Proceeds benefit the Music & Memory Foundation and the Utah Film Center. Tickets are $25. (Niesel)
