You know those bands, the ones that maybe you’ve heard of before, but never heard a song of theirs, but are most likely completely new to you. The ones that are pleasant surprises. The ones that are almost better than the main act you came to see. This was how I started listening to Lostprophets (who opened for Hoobastank), and also One Republic (who opened for John Mayer). It’s how I heard of these guys, when they opened for Mumford. So good.
