I've seen this guy a few times now and I'm always glad I did - his energy & genuine enthusiasm is infectious. On top of that, he's got impressive skills - if there's a better plastic bucket drummer out there, I've yet to see them.
Seems a cunning set up actually - I bet they all fit into each other for a compact, robust and portable act with good novelty appeal. No electric amplification needed either. All in all a gold star member of the busking fraternity.
