| A two-feel just means playing two notes to a bar - so usually on the 1 and 3.
Jaco is all over the place on the main section of Punk Jazz at different times, but there is also a very slow section which is probably what he means by half time.
He does play 1 and 3 sometimes and sometimes goes into 4 - with all sorts of fills and syncopations.
I've discussed this with Chris F before and I think it's what we would call a "broken two feel"
