GREAT theme to PHANTASM:

I hope someone comes along and re-makes this movie someday.  I like some ideas of the original but overall I thought the movie was a bit of a mess.  And the inexperience of the actors really shows.  Though it has its "cult" charm, I suppose..

And of course, Goblin is fantastic, especially their work on DEEP RED and SUSPIRIA.  This is my favorite of theirs:

RETURN TO GLENNASCAUL (1953) has the most perfect harp music for their ghost story, not the very opener but thru the whole 20 minute story:
