Jamie Lidell still does.
He has made some major mods to an Otari 5050 4 track, and combined this with a whole variety of clever electronics to do some amazing work. This video is eight and a half minutes long and jam packed with cool ideas, and cool sounds This has got to be the best video i’ve seen in a long time. A gem.
(The video production here is amazing too. Like for instance the focus change to his face.)
I’ve done stuff with multi-track tape loops on reel to reel equipment before and this has me GASing to go back.
