i brought the JJ cd the other day...
CD 1 is nice and chilled house, put disc 2 on expecting it to get pumping but unfortunately it didn't. Just funk classics
No trademark JJ trickery either... sadly it's just plain old compilation style beat mixing... again... nothing adventurous, nowt gained. He could have quite easily mixed that with his toes!!!
In my opinion if you've already brought a chillout album this year and got some old funk mixes don't bother.
Can't comment on the other...
