Getting into jazz just a few years ago led me into getting more exposure to Blakey’s playing. Those Jazz Messengers Blue Notes can be found easily on the used market and as a result I picked up a bunch. Definitely enjoy Blakey’s style. For whatever reason, when looking back on those initial buying days it does seem that Roach’s albums, outside of those with Clifford Brown, just aren’t as ubiquitous. So I haven’t listened to him as much.
I first really tuned in to Roach’s playing on Slide Hampton’s Drum Suite. Roach blew me away on that one. Definitely the first time I picked up on what others have described as him playing the kit like a horn. It was an intense experience.
Based on that, I’d go Roach here but mainly because I’m not as familiar. Would be interesting on a blind test if I could pick out either one. I have my doubts in that regard. I don’t think Roach growled as much as Blakey, so that would be a major hint I guess.
