warming up is critical. It makes such a difference. And I would wonder why the first couple of songs in a set, it takes me a couple of songs to get warmed up and I wish I could start off as good as I get by the third song in. I remember well, I was actually at a gig, you know, Stanley Clark does a thing at the music school where he has all kinds of musicians playing. And I'm looking at the old jazz drummer in the dressing room warming up. I wouldn't be content warming up. That seems so lame. That's like so, you know, but actually there's the old wisdom-doll profession. If it's good enough for him, it's good enough for me. So just simple rudiments, single stroke rolls, paradiddles, just to get the blood flowing, to get this nero's happening, the signapses connecting, it makes a huge, huge difference. And I can tell because when I start, it's a bit stiff, but I keep going and it gets much better. And so that warm up. And the other thing is, stretch is, this works really, really well. You know, you can put for drummers, you pull every muscle here, that muscle, that's that muscle there. This muscle here is that muscle there. And you know, the anatomy of the forearm and the fingers, and this makes huge difference. And it looks like, it doesn't look that professional, but believe me, it makes a huge difference.
