As a part of the 12-week outdoor dance series at Playhouse Square, local dance instructors will lead Dancing Under the Stars tonight at U.S. Bank Plaza. If you aren't familiar with salsa, then you won't want to miss the fun instruction at 6 from the staffers at Viva Dance Studio. Then, from 6:30 to 9 p.m., the plaza turns into a massive, fun-filled dance party featuring a live band. (This week, it's Grupo Tumba'o.) Admission is free. Find a complete schedule on the website.
