Los Lobos Three dozen years and more than a dozen albums into its career, the band could be forgiven for pursuing the most relaxed, comfortable way to make a new record. But from the early exuberance of its 1983 EP, “… And a Time to Dance,” to the musical and sonic sophistication of 2006’s “The Town and the City,” Los Lobos has long strived to push itself, and its music, to new places, and that’s no exception for “Tin Can Trust.” Amoeba Music, 6400 Sunset Blvd., Hollywood. 7 p.m. Free. www.amoeba.com.
