"If the drummer is playing 5/4 while the rest of the band continues in disciplined 4/4 until it meets up again (basically 20 beats), is it a time change? Sheet music says no, but the feel says Yes."

I wonder if you could do this tastefully with other combinations of time signatrues that will meet at their multiples. Anybody crazy enough to actually try that ? (I'm just barely at the desire to write songs - no where near playing with the time signatures yet : )
