Gig!
I found myself a multi-band Sunday afternoon gig to go to! An underground indie-rock venue called Hiroshima 4.14.
It actually took about 20 minutes of wandering back and forth to find the way in!
English translation of the band names:
The C-G/Orekaba/AXE/Ohirudake/MARUX/In a short while.
I may well be the oldest person here apart from the stage director (?) and the sound man, so nothing unusual there!
