Here's a bright proto-disco groove from Bernard Purdie, on the tune Funk Down, from Mongo Santamaria's Afro-Indio record:
The snare drum filler notes on the es happen more regularly, and more emphatically, than notes on the as, which are more random. Phrase transitions happen with a crash on the & of 4— mostly with cymbal and bass drum, occasionally with cymbal and snare.
Drat, I thought this one was on YouTube, but there's nothing but a technoid remix, with a mutilated Purdie track. This dance guy will tell you what's a funky drum part, so shut up, Purdie! I guess you'll just have to buy the record.
