Friday: It might not be the best season to hear "Runaway Train" echoing through the Twins' ballpark, but it's about time the team hosted a rock concert at its heretofore Kenny Chesney-monopolized stadium.

Soul Asylum, Big Head Todd & the Monsters and Matthew Sweet are all performing their best-known '90s albums in their entirety for the outing.
