Duo ad.lib "Remix" The composers performance duo "ad lib." (Julius Holtz, live electronics and Andreas Staffel, piano) transmits the Remix techniques into contemporary music. By means of fragmentation, adjustment of tempos, recontextualization and collages, compositions of contemporary instrumental and acousmatic music are remixed. REMIX creates a hybrid fusions of pieces - or contrasts works among each other. Julius Holtz and Andreas Staffel fuse the Remix starting from a combination of live-electronic music and instrumental piano performance.
