Nice, I haven't exactly listened to everything, because I don't like how their sound changed later on either, and I prefer their harder stuff with John, Greg's a little bit more synthy, and I don't like that as much- it's not Petra to me. I'm collecting all albums from Back To The Street through Wake Up Call. I just need On Fire!, This Means War!, & Petra Praise: The Rock Cries Out. Then I'll be complete- but I want Beat The System too, once I'm done with collecting the John albums I want I'll listen to more of Greg's stuff.
