Camden vocalist and voice instructor Anna Dembska is part of a two-concert weekend at The Cannery @ South Penobscot, 207 Southern Bay Road.

Dembska will perform Friday, Sept. 30, during an evening featuring Thomas Buckner that begins at 7 p.m. Baritone Buckner, who for decades has championed music of the avant-garde in America and throughout the world, will perform a solo set of commissioned pieces, one with video projection, followed by a group improvisation with Dembska, Steve Norton (reeds) and Leslie Ross (bassoon).

Buckner has appeared at Lincoln Center, Carnegie Hall, the Herbst Theatre, the Art Institute of Chicago, the Berlin Spring Festival, the Huddersfield Contemporary Music Festival, the Prague Spring Festival, and the Angelica Festival of Bologna; and is featured on more than 50 recordings.

Sunday, Oct. 2, at 7 p.m., legendary performer and virtuoso guitarist/banjoist Eugene Chadbourne, accompanied by Farmington's Gustavo Aguilar on percussion, will play his own. With a discography of more than 200 albums, Chadbourne has been an icon of the American underground indie scene for four decades, offering outrageously inventive, genre-bending interpretations of everything in American music from country to folk to bluegrass to free jazz to noise.

Concert admission is by donation, suggested at $5 to $15. For more information, visit  The Cannery at South Penobscot’s Facebook page.
