Many invited musicians from Japan and overseas will perform improvised music over a 2-day period, for 7 hours each day. On both days, about 8 groups of varying formations ― duos, trios and larger ensembles ― will each perform for about 30-40 minutes. In addition to Japanese musicians there will be musicians from the UK, Germany, Austria, France, China, Korea and Singapore, for a total of about 40 artists. They play a wide range of instruments, from conventional acoustic instruments to computers, electronics, and self-made instruments, from which various types of music are created. Over these 2 days you can witness performances at the forefront of contemporary improvised music.
