Elvis Presley, Johnny Cash, and other greats recorded at Sun Studio in Memphis, TN. It's still there (after a spotty history, including resale and re-opening in the late '80s) -- and it's still analog. Mostly analog, at least; a Pro Tools system is there for people who don't want to pay for an all-analog production. Thousands of tourists (I met a family from Norway who'd come to visit Graceland and Sun) descend on the old building each year just to see the place, and others come to record in the legendary space and what has become a boutique recording studio. I got to chat for a while with Sun recording engineer Matt Ross-Spang about working with the studio's lovingly gathered and restored recording gear, some of it nearly three times as old as he is. (An unexpected bonus: hanging out for a few hours in the Sun control room is a good way to bump into Fluke Holland, former drummer for Carl Perkins and Johnny Cash, who stopped in just after we stopped shooting.) Be warned: there are some bursts of rock-and-roll to listen through.
