Sunday Happenings

Sonic Youth at a more youthful stage of its life from Myspace.

After 28 years, 16 studio albums, and countless other recordings, you've had enough time to decide whether or not you like Sonic Youth. The standard-bearers for the avant-garde impulse in rock need an army of guitars to play their repertoire, but not a detuned string or sawn-apart bridge is wasted. Less familiar to younger fans might be the headliner, the New Jersey strum rock band the Feelies, which has the existence of R.E.M. on its hands. It's the Feelies first appearance in Boston since the band broke up 17 years ago. Wilbur Theatre, 246 Tremont St., 7:30 p.m. $29.50.

Tone Clusters

Swedish composer Thomas Jennefelt rarely gets performed on these shores, which makes the Boston Choral Ensemble's performance of his seven-movement symphony for voices Villarosa Sequences something special indeed. It's the North American premiere of this minimalist behemoth. Old South Church, 645 Boylston St., 2:30 p.m. $34/$30.

Yard Sales

The Papercut Zine Library, the free library that lends zines and other underground published material, subsists entirely on donations. Give the organization a boost this afternoon at its indoor yard sale, featuring books, records, clothes, and more. The Democracy Center, 45 Mt. Auburn St., Cambridge, 11 a.m. onward. Free.
