I don't normally bother mentioning things from
RockyMusic.org on here, since well... there's only a limited set of Rocky Horror audio freaks. This recent addition is of wider interest though, I think:
http://www.rockymusic.org/mp3scat/rhs-belascolive/These MP3 sound files are from a live recording made on March 14th, 1975 of the (very short-lived) Rocky Horror Show's original run at the Belasco Theatre on Broadway. It was taken from a 1/4" reel-to-reel tape kept by one of the sound engineers at the Belasco (whom a fan had ruthlessly tracked down and bribed!). The show opened on March 10th, 1975 (and then quickly closed less than a month later), so this was one of the first few shows.
It features performances by Tim Curry as Dr. Frank-N-Furter, Richard O'Brien as Riff Raff, and Meat Loaf as Eddie/Dr. Scott. The quality is excellent, and the recording is of the complete show (including all dialogue). It's very listenable, though some of the dialogue does get very low in volume and is occasionally overpowered by audience reactions. It's fantastic being able to hear Richard O'Brien, Tim Curry, and Meat Loaf all on stage together though. I really like hearing Meat Loaf doing Dr. Scott - he's practically the only person I can hear singing toward the end of Wild And Untamed Thing. Tim Curry's ad libs can be pretty amusing too. At any rate, check it out if you like.
