I know you work with professional drummers and when it's time to record, a metronome is used.....My question is, my drummer has been playing on an off for 16 years and I noticed when we practice or play live....he rushes his fills or sometimes he gets too fast during steady paced parts. Any way to prevent him from rushing? He dosen't think he's going to fast...but I do notice it and call him out on it. Does he need to practice with a metronome? Any advice would be appreciated.
