This is a photo of the Wally Heider Recording truck on location during the recording of Boston, Long Beach 77\’.
I was on the sound crew for Boston and I happened to take the photo. It is fairly low res. but it might be good for this site. The recording can be heard on Wolfgangsvault.com It was a memorable experience as we had phantom power problems that day …. we eventually sorted it out and I think the excitement of that show was captured by Wally\’s team as it was.
