you may well be right thereAgree with you on everyting but this...to the average joe (non-drummer), Dennis's solo was probably more than enough to impress...it's just us drummers that knew he had more in him and wanted more!...
never been a massive dennis chambers fan either so might be slightly biased!
although that said he doesn't exactly look the most excited and it barely even looks taxing to him so although what he is playing is great he makes it look "too easy" maybe?
its all subjective just voicing how i felt, as you say sometimes it can be a hinderance to be well informed on the subject (i.e. be a drummer rather than a non drummer)
