I agree, a lot of bands on Fearless get big in the scene eventually except for Sparks the Rescue.
I'm a longtime Sparks fan and they rarely get any exposure. For a band that could easily get a solid fanbase from ATL, Mayday Parade, The Maine, etc. crowds, hardly any scene kid knows them. Sparks could've easily fit in with the first Fearless Friends Tour with Mayday Parade or at least support The Maine. I remember they were originally supposed to be on the A Rocket to the Moon Spring 2011 tour, but was unable to get the funds so they were replaced by Runner Runner. I think the main reason why Worst Thing I've been Cursed With was unsuccessful was because Fearless didn't promote them enough.
I think Fearless has some great bands on their label, but if you're not screaming right now or Mayday Parade/ The Maine it doesn't look like you'll get much help. I wish Tonight Alive wasn't signed to Fearless but at least they're already being promoted with the current Fearless Friends Tour.
