With lyrics that are as innocent as an eikaiwa lesson, the song that's got me moving most these days is Nice to Meet You (Na Na Na). It's an essential crowd-pleaser during their short but frenetic sets, and it's guaranteed to stick in your head for days to come.
Worth a listen also is the massively perverted New Girl, though I don't believe the band have caught the perfect performance yet. The version linked above is a solo performance from enigmatic frontman, Sakura, recorded in his kitchen on a broken laptop. It's got the requisite Robert Johnson-isms. I think that's all he was really after.
Not the most far-out band in my record collection, but one that I look forward to hearing more from. Spread the word!
