Hi, Jio_Fleed_on_The_Roof,
I just listened to Judgement Day, as suggested by one of the other people in this thread, and felt the violin player actually sounded very classical throughout almost the whole piece, using traditional vibrato, chorRAB, etc. The song I heard reminded me of one of my favorite Suzuki method violin pieces I played as a child ("La Folia"), which I always loved because it has anger and intensity that well up as the piece progresses. Have you considered just taking some existing classical pieces that have this sound and modifying them to create the song you want?
