One of the ones I love to see in surround is Los Lobos Kiko, the classic debut Big Country The Crossing, and my all-time favorite album Buckner and Garcia's Pac-Man Fever. Haha... but seriously those video game tunes would sound pretty awesome in surround. An Australian band, Ballpark Music, used similar vintage video game audio rather effectively in one of their earlier tracks.
Also Capital/UMG already did Crowded House and Richard Thompson so how about something like the Tubes Outside / Inside or another J Geils Band perennial favorite of mine Freeze Frame.
Also the late great Talk Talk's gorgeous later albums would sound sensational in surround
From comments previously mentioned:
Steven Wilson showed a picture of the Cars' debut in one of his audio talks so I have to assume that's coming out sometime in the near future. Hopefully not all the way to 50th anniversary in 2028!
Ken Scott is ready and willing to remix Crime of the Century in surround... I hope he gets that opportunity.
i know Frankie Goes to Hollywood's Welcome to the Pleasuredome is coming before November as a Steven Wilson special. Great production by Trevor Horn-- so that should be a gem.
