Probably a safe bet that Puffy's set will be curtailed like most of their festival appearances, but for a two day event there are a lot of acts across a handful of stages. Add Puffy to everyone else that will be performing and MONSTER baSH offers a compelling event: Kaela Kimura, the telephones, Asian Kung Fu Generation, Shishamo, Base Ball Bear, Magokoro Brothers, Tokyo Ska Paradise Orchestra, etc. Lots to see to say the least. I will be curious to see what Puffy's set list and band looks like for this appearance and the forthcoming tour.
P.S. I had a blog all plotted for the SMA 40 appearance Puffy had, but Sony in their not-knowing-how-the-internet-works style pulled the YouTube vids. Honestly, YouTube is one of the best marketing tools that a company can use and keep interest in their artists. Oh well... It will probably pop up again and I will snag it.
