Wilco is still in the midst of its fall tour through the United States, with a breach of the 49th Parallel for two shows in Toronto next week. Come February 2010, the tables will turn for a TransCanada tour, from British Columbia to Nova Scotia, with a half dozen stops planned for south of the border. The Canadian leg beings with a free concert for the "Live City" Vancouver celebration of the 2010 Winter Olympics.

Christina Courtin begins a three-week tour of the United States with Brooklyn trio Elizabeth & the Catapult in Pittsburgh, Pennsylvania, tomorrow night.

Punch Brothers' fall tour is headed to the University of Michigan's Power Center in Ann Arbor tonight. Though the band's 2008 Nonesuch debut, Punch, also marks the band's first as Punch Brothers, "they’ve already made their mark on the newgrass/new-acoustic scene," says AnnArbor.com in an interview with fiddler Gabe Witcher, "as they’ve created their own, unique variation on that ambitious hybrid of bluegrass, jazz and classical-music elements."

Brad Mehldau begins the jazz series he's programmed at London's Wigmore Hall in a duo concert with Joshua Redman next week. NPR's jazz blog A Blog Supreme recently listed the pianist's recordings as the best introduction to the jazz of today, citing his 2002 Jon Brion–produced Largo as chief among them. "This album was a big one for me," said one panelist. "It fuses masterful jazz improvisation with modern rock production."

And St. Louis welcomed Wilco to the Farm Aid benefit concert for a set Rolling Stone says "brought the crowd to its feet."

Wilco plays the annual Farm Aid benefit concert, which will be broadcast live on DIRECTV and online on Sunday.

Alarm Will Sound will celebrate its recent Nonesuch debut, a/rhythmia, with a free album release party and listening event at New York City's (Le) Poisson Rouge on October 18.

Summer may be the season of festivals, but this fall weekend has two standouts: Austin City Limits and San Francisco's Hardly Strictly Bluegrass, a free outdoor event that has three Nonesuch artists—Emmylou Harris, Allen Toussaint, and Amadou & Mariam—set to perform in Golden Gate Park. Both Harris and Amadou & Mariam have concerts in LA earlier in the week; the latter plays live on KCRW this morning.

Chris Thile brings his Mandolin Concerto to the third city in as many weeks in a performance with the Alabama Symphony Orchestra in Birmingham tonight. Thile joined the Oregon Symphony this past weekend for the West Coast premiere of the piece. The Oregonian called it "nothing less than a reinvention of the possibilities of his instrument" from the "mandolin wizard."
