Lowrider Band’s core foursome is partially responsible for some of the most popular, exciting music of the 1970s. They lost a legal battle with ex-War bandmate Lonnie Jordan that prevents them from using that famous name in any of their promotion, but these hombres—including guitarist Howard Scott and harmonica player Lee Oskar—will bust out poignant and invigorating Latinized funk-soul hits like “Slippin’ into Darkness,” “The World Is a Ghetto,” and “Low Rider,” of course.
