I can play with a drum machine better than a Russian Dragon. I'd prefer both to neither. But groove means nothing without time. I'm not talking subtle shift of speeding up or slowing down. I am talking 5 or more bpm difference in a 4 bar phrase kind of bad time keeping.
Yes but if you were stuck on an island with that drummer and a metrome, it would be fixable.
You make someone hit the click for hours until he doesn't hear the clock anymore, or make him play to a metronome and you will see improvement.
Groove is really something else, i had a friend drummer that said it's a matter of how the track is produced.
He is a very stressed and un laidback person.
He denies there is a issue
