Through the wonder that is Youtube, a Japanese rock band named Girlfriend was recommended to me. I have no idea what the lyrics are (seems like girlpop from what I can gather), but the bassist is choice! Great lines, a lot of movement that still drives the song, plays better than the lead player (or me). Really an eyeopener for me. Seems Japan is keeper rock alive while the US mines the rap/hiphop segment. And that has lead me to other examples of Japanese rock and metal that are interesting.
