Yes. It's a Nintendo Entertainment System. Plus, four guys with instruments.
Anamanaguchi opened for a band I saw last night called “PEELANDER-Z”. While the latter was more entertaining, the music of Anamanaguchi was actually really good. 8-Bit “Chiptunes" mixed with traditional instruments (guitar, drums, bass)… it's a winning combination for any past or present legacy gamer.
First CD I've bought in a long time, and it was only $8 at the show! Check them out for sure.
