Delays and Overdubs

It was about 50 years ago that the Beatles changed music significantly.  It wasn't just the backbeat, twangy guitars and mopish hairdos.  They were pioneers in the studio using multitrack recording techniques.  They were among the early adopters of technology that let them play multiple parts in a single song by overdubbing.  It was all made possible by a design of a tape head that could simultaneously playback and record on different tracks, but that isn't important right now.  The key thing is that that technology has evolved since those days.  Now there are digital delay lines that let you record multiple tracks and then layer more sound on top of them as they loop.  You may recall my friend Fabio's foray into the use of delay lines to perform with himself.  Here are two more fine examples of one-man-bands who play complex songs by overlaying multiple tracks.  Nice job guys!
