Welcome to On the Radar, where we preview up-and-coming arts events to mark your calendar for. It’s hard enough to wrangle a hip group of artists/musicians/designers/models together at the same place and time, but it’s even harder to convince anyone to come see the spectacle. The visionaries at Square One do just that with scenester-crowded, can’t-miss-‘em shindigs — like this Saturday's eco-themed Magnum Opus — that draw party people in droves.

More than 75 visual artists display their work (among them CL faves like Blue Lucy, Kat Wilson, KLAAREN and Robert Wegmann), Jeremy Gloff hosts his album release party, and dance and fashion shows by Bella Danza, Enigma Dance Kru, Kinetic Dance Group and Wear To The Tear Fashion mean that there's always something shiny and new to look at onstage. The cherry on top is that this nightlong art extravaganza is completely gratis. Sat., Nov. 14, 7-10 p.m. , The Ritz Ybor, 1503 E. Seventh Ave., Ybor City, free, squareoneflorida.com. – Franki Weddington
