311’s SA Martinez and Ryan Siegel from Exes Of Evil formed Los Stellarians in Ojai while bonding over vintage ’70s soul. Their first record, “Cholo Soul,” came out in 2014, consisting of classic covers inspired by Martinez’ record collection. They followed it with “The Mas Chingon,” an album of originals, that same year. On their recently released third album, “Rucaz n Rolaz,” the band went in a grittier direction, honing in on lowrider Latino culture and harder funk. L.A. 10-piece tropifunk band The Jungle Fire and hard rockers Strata open the show.
