The East River Folk Society is a Downriver-based, 501(c)(3) nonprofit organization, which celebrates the joy of music with monthly, public “musical coffee house” performances in an open-microphone format. These performances feature a variety of local musicians showcasing their talents in a relaxed, comfortable, smoke-free, fun setting. The open-mic format attracts numerous performers of all ages and levels of ability from across the Downriver Detroit area.

At a typical coffee house performance, a dozen or more acts perform sets of two or three songs each, depending upon time constraints. The show generally consists of two approximately one-hour segments, with an intermission. An assortment of snacks, soft drinks and coffees, is also available for a small donation. The requested donation fee for the event is $4 ($3 for performing musicians and members) at the door. For select, special events (like certain benefits for local charities/causes), it is $5.

The East River Folk Society coffee house performances are held on the second Saturday of each month during their September-to-June season, hosted at the First Presbyterian Church's fellowship hall (which the Society rents) at 2250 Oak (at 23rd; just east of Fort Street) in Wyandotte, Michigan.
