So you can imagine my surprise and delight when iTunes started carrying their albums around November of last year. The U.S. iTunes store even. I've since stocked up bought 20 or so songs of theirs and have yet to be disappointed. The best I can tell, the U.S. iTunes store is selling all of their albums.
To top it all off, Shina Ringo's latest album, 三文ゴシップ (sanmon gossip) not only includes the 2006 Karisome Otome single, but includes another awesome collaboration with Soil and Pimp Sessions: マヤカシ優男 (Mayakashi Yasaotoko). There isn't a video for it, but you can preview the song on YouTube. Don't worry, the lyrics for this song are all in English.
Even though they are a Japanese band, since it is jazz, most of the songs have no lyrics. That said, What few words there are do tend to be English. Which makes them a very approachable band to international audiences. In fact, right now they are in the middle of a European Tour. They have a live show schedule on their web site; I know I'll be watching to see when they come to San Francisco.
