At a Minneapolis recording studio, Sound 80, everyone from Bob Dylan to Dave Brubeck to the St. Paul Chamber Orchestra recorded music during the 1970s. And it was at Sound 80 in 1978 where the SPCO made one of the first digital recordings to be released commercially.
The music was captured on a prototype digital recorder created by 3M. The engineers were impressed with how it eliminated the wow and flutter of analog recordings.
