They are:
Emotional - as noted by singer Nabi Sue Bersche when she asked if it's wrong when your own song makes you cry; it's because you mean it,
Powerful - just listen to their tunes,
Energetic - check out the photos.
I'm predicting that they'll be on the main stage next year for sure.
Check out some tunes. "St. Cecilia" is a guaranteed hit single, "New Survival" is a great closing tune, and Kate Bush's "Running Up That Hill" is a fantastic signature cover. The rest are deftly crafted and powerful songs that have immediate appeal and lasting depth.
