But, I don't think any arranger should ever write a drum part for a drummer because if a drummer can't create his own Interpretation of the chart and he plays everything that's written, he becomes mechanical he has no freedom.
I can't sit down long enough to absorb any kind of learning.
I think the drummer should sit back there and play some drums, and never mind about the tunes. Just get up there and wail behind whoever is sitting up there playing the solo. And this is what is lacking, definitely lacking in music today.
But I think that any young drummer starting out today should get himself a great teacher and learn all there is to know about the instrument that he wants to play.
