A Cooler Exercise for Clarinet, Vibraphone and Piano by Mathias Rüegg. Doblinger, 2011, SS, includes parts and piano score. Mathias Rüegg (1952-) who was born in Switzerland is a musician, composer, and bandleader best known as founder and director of the Vienna Art Orchestra from 1977 to 2010. This piece clearly has a jazz influence. It has many tempo changes and quite a bit of mixed meter but all of the whole beat variety (2/4, 3/4, 4/4). College level with a duration of about 4 minutes.
