And man, Erin's got good taste.
Kelsey has a really unique strong voice. It's a little off on my ears, almost sounding like something auto-tuned, but in reality she's just got that much control over how her singing voice forms words and create the melodies. She's also got the unique teenage strength and feelings behind what she's singing out to the world.
Hopefully more comes from Kelsey - I'm sure looking forward to it!
