I first saw this movie in the 70s as a double bill with "The Rocky Horror Picture Show", which was the film I actually went to see. I'd never heard of "Phantom" before, but enjoyed it far more than "TRHPS". The movie is best described as a black comedy/theatrical rock/horror/fantasy, you'll see what I mean. Based loosely around the "Phantom Of The Opera" story and the legend of "Faust", but in a modern (70's) rock setting. Directed by the now legendary Brian De Palma, he brings excellent performances from Paul Williams (deminutive American singer/songwriter, best known in the UK for the "Bugsy Malone" score) as the villan, Gerrit Graham as the brilliantly camp character "Beef", and William Finley as the "Phantom" (how anyone can convey such emotion with just one eye showing still amazes me). De Palma also uses his split screen technique to good effect. Looks very dated, but apparently a cult classic now (I thought it was just me). This is a movie you'll love or hate. Definately different. Hope this was helpful to you.
