In three months, Chris Jamison went from Capital University mailman to "The Voice" finalist.

Why did you choose John Mayer's "Gravity" for your "The Voice" blind audition? My freshman year at college, I joined the rock ensemble at Capital University, and "Gravity" was the first song I sang. For the blind audition, I thought it'd be perfect because, No. 1, I knew it. And I knew in that moment, I'd be nervous and scared-the last thing I wanted to think about was the lyrics. I knew I could create this version of "Gravity" that, in 90 seconds, I could show off exactly what I could do with my voice.

What was the best piece of advice Adam Levine gave you? I don't know exactly how he worded it, but it was to never strive for perfection. A lot of times you go on the "Voice" stage, and you only have that one song to get you to the next round. During a commercial break, two times, he came up on stage and said: "Just sing the song. Don't worry about anything else; don't worry about what's on the line here. Just keep it simple."

What surprised you about the reality TV experience? Like anyone else, I'd only seen Adam Levine, Gwen Stefani, Pharrell [Williams] and Blake [Shelton] on television and in magazines. When I did the blind audition and those chairs turned and they were right there in front of me, they looked fake. Gwen is just a normal mom. She drives a minivan to the set. Pharrell is very easy to talk to. They're normal people who just got a lucky break, and they work really hard to get where they are. Anytime I need advice, [Adam] always picks up the phone.

Since the show ended, you and your band have been staying busy. The guys I play with, we played all through college, so I knew I [still] wanted these guys backing me up on stage. There's a different vibe than if I were up there with five guys I'd hired and had no relationship with.
