Local artist “Uncle” Charlie Hardwick, who is known for this eye-popping rock concert posters, is the featured artist at the fall edition of the Bayou City Arts Festival. Hardwick, who is legally blind, has created posters for, among others, James Brown, Metallica, U2 and the Red Hot Chili Peppers.

Among the highlights of the downtown festival — there’s another each spring at Memorial Park — is Art on Water, which features floating artwork on the reflection pond, and the Art of Wine, a tent that offers wine tastings and cooking demonstrations.

Produced by the Art Colony Association, the event features more than 300 artists working in a vast range of materials, from photography and print-making to gold and gemstones. In its 40-year run, the festival has raised more than $2.7 million for nonprofit groups such as the Heritage Society, the Art League and the YMCA.
