Psychedelic rock & blues harmonica virtuoso Ottomatic Slim (aka Otto Lenz) teams up with A-list guitarists to deliver a high-energy blend of deep-groove blues and raw rock power.
​A descendant of the late great Chicago gypsy swing guitarist Chick Johnston, Slim carries forward a rich musical lineage. He has been featured nationally and internationally on both commercial and college radio stations, earning widespread acclaim for his electric live performances.
