Filtersphere 4 perform in the gallery 25/11/2023, ambient improvisation, guitars fx drums, voice fx 

This is Filtersphere's 4th appearance.
John Kingston - guitar, James Gilberd - drums, Nigel Baxter - voice.
Filtersphere formed in 2023 and has to date each performance has been a single improvised piece. This one, at 40 minutes, is the longest to date.
There is extensive use of guitar effects pedals and E-bow. The drums range in age from 50 to 90+ years and several have original calfskin heads. The bass drums are 22", 26" and 29".
Apologies for the video quality. I accidentally left the Sony Handycam switched to Super Nightshot mode, which is why it looks like security video.
