Type donk into youtube, knock yourself out. I personally think 'Put a Donk on it' was the peak of the genre. I'd fucking love that shit if I was 16 and could triple drop again.
I was browsing in HMV ages ago and I actually saw the album by them (Blackout Crew) on the shelves. I was so tempted to grab it for the lols.
Speaking of brick and mortars, I'm having no luck finding the special edition of Noisia's "Split The Atom" so I might just grab it on iTunes or Amazon.
EDIT: yes, I still buy physical media.
