If you’re interested in modern Christian rock, I recommend the following:
Fireflight (Powerful female vocalist)
Flyleaf (Another power female vocalist)
Skillet (Messages of hope)
Switchfoot (Powerful lyricist and lead)
Thousand Foot Krutch (Good band to mosh to)
These bands are on constant rotation in my playlists along with more secular rock/metal bands.
What, no Third Day?
