Barry Beckett, RIP
The specifics are in the link above, but if you think you’ve never heard of Barry Beckett, I can promise that you’ve probably heard him. For a pretty good listing of his production work and the countless albums he appeared on as a keyboard player, check out discogs.com.
Beckett played on many of rock, country, and soul’s most important records as one of the “Swampers”, the Muscle Shoals rhythm section. Checking out his discography is like getting a history lesson in pop music from the last fifty years, and he’s played with everyone from Bob Dylan to Tony Orlando.
You can find lots of clips online which feature Beckett in some manner, but here’s a nice one just posted as a tribute to him:
