As a member of the Mark Morris Dance Group since 2002, Noah Vinson has enjoyed touring the world. This time around, he won't be helping with the Mark Morris Dance Group's extensive community engagement efforts. He has in the past. Five of the 18 members of the Brooklyn, N.Y.-based dance company arrived here earlier this week to lead 27 community engagement events — more than any other performing arts group that passes through Krannert Center.
