Last month I played in a project called Sound Relay, which was a collaboration between Ensemble 10/10 (the Liverpool Philharmonic's contemporary music ensemble), and the a.P.A.t.T. Orchestra. The project was part of the Liverpool Biennial's Long Night.
The musicians were split into groups starting at different locations. I was stationed initially at FACT. Starting at the Liverpool Philharmonic Hall, the first group of musicians walked to FACT, playing along the way; then we went to the Bluecoat, still playing; and made our final stop at Tate Liverpool, where we split up into different groups, each in a separate room in the gallery.
Here's a video with highlights of the whole event.
