Doppelganger is a solo for timpani which utilizes a multipercussion setup of concert toms, woodblock, sizzle cymbal, and wind gong. It is an ideal selection for percussionists looking to perform a dramatic and virtuosic timpani solo that weaves new timbres and interesting patterns of coordination. Kirk J. Gay composed and dedicated this piece to his good friend John W. Parks IV, associate professor of percussion at Florida State University (seen in the video performance of the piece).
