I'm taking part in the Guiness Book of World Record's Longest Concert with my boss (Kitagawa-Sensei) and another musican, Imamura-San! We'll be playing for about 2 hours.
Unfortunately, I don't even know how to get there, myself. So for now, I'll just post any info that I do know.
Where: Somewhere in Hikone, Shiga-ken, Japan
What: World's Longest Concert - A week long!
When: Sat. March 24th, 10:00pm-11:pm, and Sun. March 25th, 12:00am-1:00am
Sorry for the lack of info thus far, hope to see you there, though!
