Just finished watching PHANTASM RAVAGER and it's as glorious a splattery mindfuck as the previous entries, with a fantastic score from returning composer Christopher L. Stone. His score for PHANTASM OBLIVION was a bit more moody and dissonant, but this one is a powerhouse with several rockin' renditions of Fred Myrow and Malcolm Seagrave's theme and even a plot summarising end credit rap!
Hopefully someone's putting this out on CD. Hopefully someone's working on the other sequels as well.
Also stumbled across this the other night and was mightily impressed.
