I'm a drummer working on timing. Have been for awhile. Been working with a click and program that tells me when, where and how much each limb is off. Really trained my ears.Having just skimmed thru these replies and listening to the recording my opinion is, USE A CLICK! Practice with it as a whole group and when you hit record ,dont tell the drummer.
The timing is definitely off.
1. The drummers timing needs improvement. He and the bass need to work with a click. You need a tighter rhythm section.
2. Bad timing isn't always the drummers fault. I can hear that everybody's timing suffers.
3. Definitely, every member needs to use a click.
But, it sounds not bad.
