If you thought vinyl LPs were going retro, that's nothing. Adventurous musicians are going back into the dark ages of recording through "The 78 Project," which uses an old Presto machine to record 78 rpm songs direct to vinyl, with the finished product ready for listen minutes later.
"Soundcheck" captured this in a recent episode and it's a fascinating trip down memory lane, and gives you an idea of the processes music historians like Alan Lomax took in the first half of the 20th century to record old blues, country and calypso in remote locations in North America.
The videos below capture the magic the musicians experience as they hear their work in a new dimension, but the audio stream of the "Soundcheck" show is especially illuminating in that you can compare analog vs. digital audio.
