"Guitars" by Gregory Block STEAMBOAT SPRINGS — You may recognize Gregory Block’s work from the mural that he painted downtown on Eighth Street a few months ago. That project was a collaboration with Steamboat Creates, and his submission, titled “Elevate,” incorporated musical instruments, performance and visual arts into the mural’s design. Now Gallery 89, which represents Block, will display a solo exhibit called “Music of Color” opening Friday. The paintings feature all different types of musical instruments — everything from the classic wooden recorder played by elementary school children to violins, piano keys, flutes and both acoustic and electric guitars — with the goal of reimagining the historic relationship between sight and sound.
