The City Gallery at Waterfront Park continues its free series of lectures — Contemporary Charleston 2009: Revelation of Process — this Sat., June 13 at 12 p.m. This week’s featured speaker is Ishmael, lecturing on something he’s quite an expert on: “Graffiti: Past, Present, and Future.”

Ishmael was born in Madrid to Cuban parents and raised in Florida. He now divides his time between Charleston and Asheville. His newest work unifies the rebellious nature of his craft (and his past) with his journey into fine art. “The work combines graphic forms with feminine organic shapes and bold masculine hard lines using fire, spray enamel, latex and ink,” according to the release from City Gallery. “Using a word of mouth, street approach to networking — stickers, live painting collaborations with musicians, shows — Ishmael enjoys an international reputation as a skilled, provocative artist.”

The series includes four more lectures, including Ben Timpson (June 20), Karin Olah (June 27), Dorothy Netherland (July 11), and Jonathan Brilliant (July 18).
