to play with 'good time', its important to understand that in music 'relative' time is more important than being in time in an absolute sense. Let us assume your drummer switches his perfect absolute time and you are also in your perfect absolute zone both not connected, chaos will be the result.As listeners one cannot generally feel a micro displacement of time when it is together, as it happens through a tune,but one immediately hears someone not in 'sync' with the current moment.The point I am making is make sure you listen to the timekeeper of the band,hopefully the drummer and shift your clock to be with him/her. If you perceive several shifts that you have to make then have a talk with the person after the gig.Its important to keep the music together and for that its important to listen and not gesticulate wildly at an erring member ( who should be listening as well), this looks bad on a stage and sounds even worse.If you have to make displacements good or bad...make them together. No point saying 'I practice with a metronome....because not many of us have unshakeable time.So the moral of the story 'listen to the music you are making'.:)
