Stevie Mackey is one of Los Angeles’ most well-respected vocal coaches so it’s no wonder his south L.A. house serves as a singer’s stage. Under the banner Taco Tuesdays, Mackey, who has worked on “The Voice,” hosts this exclusive, invite-only monthly gathering which boasts no list, no RSVP, no Hollywood bullshit. Taco Tuesday has become a safe haven for individuals to perform, eat and commune.
