As the music community at large mourns the loss of another great contributor to its canon, several artists have also posted tributes to the late producer.   

Olsen produced international rock superstars Scorpions' 1990 ablum, Crazy World. The band posted a touching tribute to Olsen.

"Keith was a wonderful guy, and the making of Crazy World was such an inspiring journey, containing outstanding songs like 'Wind Of Change' and 'Send Me An Angel,' which had the Keith Olsen touch on every single note. Our hearts and prayers go out to his family. RIP Keith. You live on in the music," they said on Facebook.

Springfield also paid tribute to Olsen on social media in a series of posts, calling out the late producers fiery studio presence, golden ears and uncanny knack for hearing a hit.

“He could be a bit of a pistol in the studio but that was part of his talent," Springfield wrote. "Sticking to his guns when some whiny artist – me – would say, ‘I don’t think that works.’... He didn't produce all those hits for all those musicians for no reason. He had a golden ear and helped so many people reach their potential. I remember playing him my demos and he picked "Jessie’s Girl" out of a batch of 15 songs and said, ‘This is a hit.’ ... I doubted him and thought there were better songs in my demo reel. Proof right there of his gift. May God give your spirit the peace and joy and the rest it deserves. You were a star maker in so many ways. God bless your memory my friend.”

While the cause of Olsen's death has not been revealed, it is clear he will be greatly missed and fondly remembered for the music and friends he made.
