American drummer/percussionist Gerry Hemingway has made his home in Switzerland since 2009. Besides his teaching and solo performances, currently, his most accomplished working band is The WHO Trio. 'WHO' stands for Wintsch/Hemingway/Oester. It's Hemingway's unconventional piano trio with Swiss partners pianist Michel Wintsch and bassist Bänz Oester.The WHO Zoo is their fifth release, beginning with Choucas (Leo, 1999) through Less Is More (Clean Feed, 2010). Each disc has been a revelation and affirmation of this trio's like-mindedness.
