Roumain is known for his community-building as well as for his signature violin sounds infused with urban and electronic influences.

Laughs are part of the learning during the free workshop as Ivy Birney 9, center, of North Yarmouth demonstrates.

Roumain will return to Portland in May for a musical event, part flash mob and part processional, with Maine musicians of all ages parading through the Arts district.
