Pretty sure Henri was joking. He's much too humble of a guy to imply that he's one of the "good" drummers...
Indeed, on both account
...even though he is most definitely all that. Love your playing Henri.
Thank you Uncle Larry
That is valid, especially for drummers trying to make in roads, but for well established, drummers with copyright protection and lawyers, I would see that as a negative to not promote the art of drumming.
Yes, joking aside, it's very valid, what make a "good" drummer goes beyond what he or she can play, it's more about the personality than the technique, anyone (almost) can copy another drummer's licks and chops, feel and approach, but you cannot have his or her personality, it's what makes them unique and it's why many artists and bands wants to play with them... as WholsTony said, if you are a player that other musicians desire to play with you, you are a good drummer, that the bit you have to figure out yourself.
As for the comment about negativity to not promote the art of drumming from a drummer to another drummer, I haven't seen it yet, all the drummers I've met, pros and non-pros have always been extremely open and helpful in every respect. the thousands of educational DVD's, methods, books, clinics, seminary is another testimony that the art of drumming is pretty much shared among drummers all over the world, as is this forum where all opinions from beginners to seasonal pros are shared on these boards.
You can only be as "good" as yourself, you're the one projecting yourself out there, let make it a worthwhile experience, even if you're not the most accomplished drummer technically.
