Revels and the Charles River Conservancy present the 3rd annual RiverSing, Boston's newest fall tradition.

From atop the Weeks Footbridge spanning Allston and Cambridge, in the glow of late afternoon sun, Revels music director George Emlen and giant puppets Osun and Poseidon will lead everyone gathered along the river in song as we celebrate the Autumnal Equinox and the beauty of the Charles River parklands and bridges.

Also featured on the bridge this year are 5 area choruses: Sharing a New Song, Boston City Singers, Musica Sacra, Halalisa Singers and Nick Page's Mystic Chorale. Plus the extraordinary vocal ensemble Libana, celebrating its 25 years in world music, will thrill us with their Balkan-style call-and-response singing across the Charles. Also on hand will be saxophone great Stan Strickland, the Mystic Drummers and the New Orleans-style Second Line Social Aid and Pleasure Society Brass Band.

We invite you to bring a bell of any size to help us ring in the season! We'll ring our official Riverbell, and thrill to Rhode Island musician Steven Jobe's one-of-a-kind reverberating gong-drum floating along the Charles on a dragon boat.

RiverSing is an event for all ages and everyone is invited to sing! (Hint: Get RiverSing lyrics in advance by emailing riversing06@yahoo.com)
