Jumpsuit’s jam is bringing on the funk. Established as an instrumental act, the original fabric of this seven-piece outfit is Marshall Dillon and Emanuel Eisele grooving on guitar, Ian Hopp thumping drums, Calvin Lund banging bass, and Courtney Ellian backing on vocals and killing the keys. The band expanded its style in September by adding the sultry songstresses Erica Francois and Madi Phyle on lead vocals. Jumpsuit’s weekly Cedar Lounge residency at Earth Rider Brewery began in June but was paused in February to focus on writing fresh material.
