Shame to have missed that deal, never heard of this release until a few minutes ago. Managed to order one in like new condition from Amazon UK shipped for 18 pounds, current exchange rate to CDN is 1.92 so CDN$35.
You can still enjoy some 5.1 mixes on the Criterion Beastie Boys Video Anthology. Unfortunately, I think it's the most we'll ever get. It's a nice set though and has a great selection of songs with alternate mixes.I would love to hear their back catalogue remixed in 5.1 but I think there's very little chance of that given the morass of sample rights clearances they'd have to re-acquire to do any remix.
Yeah I picked that one up when it originally came out about 15 years ago - another one I haven't listened to in a while but the 5.1 mixes sounded like they'd taken the stereo mixes and added reverb to the rear speakers, or in some cases tried to make 5.1 mixes out of the instrumental and acapella versions of songs (ie instruments in the front two and vocals in the front 3) but again not the surround extravaganza I was hoping for given the nature of the music.
