Curated by R.E.M. guitarist Peter Buck, the 2015 edition of the Todos Santos Music Festival kicked off last weekend (Jan. 15-17) with performances by the Old 97’s, the Jayhawks, the Autumn Defense and Live’s Ed Kowalczyk.

The event was what fans have come to expect from Todos Santos Music Festival: Besides stellar performances, the days were packed with surprising collaborations, often finding Buck jumping onstage with many of the acts. And on top of that, Scott McCaughey, Steve Wynn, Kevin Kinney and Kurt Bloch all thrilled the crowd with surprise appearances throughout the weekend.
