Hello, I was looking through soulfuldetroit.com , taking the studio tour and saw that United Sound was in shambles( let alone all the others that are gone!)and I thoght how shameful it was, I mean ,they even left instruments just to rot,well I clicked a link, and found that they were giving tours of the building so I do hope that this recording history is saved. I did also find out that Motowns Woodward ave bld. was torn down for the Superbowl! I do believe that's where Marvin mixed the "Detroit Mix" of What's Going On" on the reissue cd at! A true shame. I do tell everyone who cah to visit Motown's museum, if they can.
