Les Paul: Chasing Sound! - DVD Clip - Sound On Sound
Early 4 track recording and infinite 'ping ponging' of the master Les Paul and wife Mary Ford.
He'd been doing this earlier but super primitive with acetates (LP's), basically recording an album then playing to it while recording another 'improved' version.
Read here how he did it while inventing all the methods we use today.
From Thomas Edison to Les Paul.
I love these records he made and especially
"Lover's Luau"!
This LP was a huge influence to the band Acetone featured on the 'Bugnoise' blog link.
