I don't know if I'd call you guys the "perfect" band to open for Ben Folds Five. Typically the opener is very similar to headliner, your stuff seems like it's in a bit of a different ball park.
Which is not bad. I think you show a lot of professionalism and true talent, more than your typical run of the mill band. The real deal, if you may. I wish you the best of luck, you deserve as much of a chance as anybody else to open for them. Try to see if you can open for other bands, too. You've got a sound that could "open" for a lot of different groups
