How about some Twisted Sister? The first 2:50 are the Viper solo, it gets really interesting at about 1:47, more like electric guitar than violin.
Heavy Metal Violin?
Vivaldi anyone?
They are fretted, come with up to 7 strings for a 7 octave range from bass to violin, and strap on so you don't get neck cramps holding them. Pretty cool...
