Nice to see my personal bass-hero playing at Glastonbury this year, Mr John Parker. Stunningly good, beatboxes at the same time, and the bass appears to double as a drum kit for him as well
This seems appropriate (being as its next week) if you fancy checking his playing out:

Anyone else seen this guy doing his thing?
