Lots of kids put together bands in high school, but most don't get to play shows with big national acts. On Sun., Aug. 29, young local band Crossing Boundaries will play a side stage at the Maroon 5 show at Trib Total Media Amphitheatre at Station Square. 

This week's MP3, "Slurring Words," from Crossing Boundaries' new full-length All That Matters, is a great sample of the four-piece's pop-infused radio rock: a Jason Mraz-like vocal rhythm with backing music in the vein of Guster. For more info, visit the band's website.
