Last weekend, Jeff Coffin hosted a sax clinic at the University of Wisconsin, Platteville. On February 6 and 7, Coffin offered instruction and also performed in a quartet with Derico Watson, Mike Seal and Alana Rocklin. Coffin has remained in the area for other clinics including one on Saturday at Cascio Interstate Music in New Berlin, WI. While in the area he also surfaced last night in Madison at an Umphrey’s McGee show. Jeff Coffin, who has been a steady collaborator with UM over the past few years, took the stage with the band at the Barrymore Theatre during the end of set one for ‘Made to Measure’ and ‘It’s About That Time.’ Umphrey’s is back at the Barrymore over the next three nights and Coffin may well return as well.
