I have never heard of that band Faith + 1, But I happen to know that Skillet, Pillar, Kutless, and Switchfoot are awesome groups.
Dont forget Pivet Plex;)!
Those bands are great and on fire for the Lord in their own personla lives. My teens and their friends love them. Here's one for you to try. Casting Crowns. Their lyrics are "in your face" to Christians and most definately needed among some circles.
