Dancers, poets and visual displays bring the music into sync with other art forms, often asking the audience to take the sound and transform it into something more.’ ‘ ‘ ‘ Stephanie Rael, the group’s publicist and wife of percussionist Eliseo Rael, said, ‘They integrate different media with each other to make it into a more fully rounded experience.’ Music alone cannot capture everything, she said, so this ‘is a different way to engage the audience.” ‘ ‘ ‘ ‘ The pieces this weekend include John Adam’s ‘American Berserk,’ a ‘high-energy work for virtuoso pianist,’ according to his Web site. Dancers from KnotDance will need to push their bodies form the staccato bursts of notes in this piece. You’ll also enjoy Eric Moe’s ‘Superhero,’ setting the stage for seeing ‘Watchmen.’ ‘ ‘ ‘ Those staying in Pittsburgh for spring break will be able to explore something unique to the area. At five bucks a pop for students, you’ve got yourself a fantastic date, and hey, you might just learn something new from KnotDance.
