YES I want this bc of reasons! He deserved so much more out of that concert. I would suggest that the people behind the scenes look at footage of ACTUAL 80’s BANDS for reference on how to do Lestat’s concert accurately.

Hit the jump for my rambling about the soundtrack…
Honestly tho, the soundtrack to IWTV was mostly orchestral, and I would imagine a re-do of that trainwreck of a movie QotD would be more … modern rock? At least 80’s, because it takes place in 1985, IIRC… more along the lines of the G ‘n R’s Sympathy for the Devil cover that plays at the end (which I still prefer to the original, because I heard this cover first!)
Or Bruce Springsteen. We know Lestat and Louis both love the Boss, don’t even try to convince me otherwise.
Elliot Goldenthal did an amazing job on the IWTV soundtrack, especially in how he perfectly captured the different characters: humorous/upbeat pieces like Lestat’s Tarantella and the more quietly disturbing Libera Me, etc.
Side note: Speaking of The American Boychoir (they sung Libera Me), I’m reminded of the Vega Choir’s cover of Radiohead’s Creep for the Social Network. That was sorta along the same lines.
