The place was in Kamiooka, a few blocks away from the Keikyuu and Subway stations. It's called Kunkunshi-raya. It was a cozy little plaze with wooden tables and chairs. The 'stage' had a piano and wooden bass, and of course amps and stuff. J and I were the only ones supposed to go, but after seeing E and C, we, or rather I, "forcefully urged" them to come with us.
My officemate K-san and another acquaintance M-san were already there. I was late because Y-san just couldn't take a hint that I really had to go at 6:30. I was able to come out 30 mins later. Good thing J didn't get tired of waiting.
The music was a welcome change of pace. It was soothing and melodious. I felt my feet tap to the percussion. My fingers were doing the bass tabs. Think "Summertime" by Norah Jones.
Here's a link from their previous performance.
I hope to catch them again soon! And also, I'd like to taste their food again because the Okinawa Yakisoba was fantastic!
