Here’s a great video of a roundtable of bassists Sharay Reed, MonoNeon, Federico Malaman, Joe Cleveland and Young Chuck.
The clip is a “cypher”, which the video explains is “anything cyclical. If you’re freestyling, you get down in a cypher (one after the other). Interrupting another man will break that cypher (unless he’s next in line and the dude behind him is falling off).”
MonoNeon shares, “Sharay Reed and Alan Snoop Evans were chatting one day and in the course of that conversation, Sharay was inspired to do a Cypher with some of the bass players that him and Snoop were aware of and enjoy listening to.” Reed kicks things off on an electric upright before passing the groove around.
