Dorothy debuts at the Crystal Bay Casino at 9 p.m. Saturday, Jan. 14, in the Crown Room. It’s a free show. Fronted by Dorothy Martin, the Los Angeles rock and roll quartet released its first album, “ROCKISDEAD,” in February 2016. The Tahoe appearance will be just the fourth show on a two-month nationwide tour. Rolling Stone named Dorothy the No. 14 Best New Band of 2014.
