One hundred and eleven cyclist have opened Harwich Festival of the Arts with a musical performance called Eine Brise.
People on their bikes rode around a designated route in the Essex town singing, ringing bells and making music with their mouths.
The piece was written by German-Argentine composer Mauricio Kagel, and is rarely practiced in the UK.
