SKF NOTE: I found this incomplete column posted awhile ago on The Great Drummers Group Facebook page. When I went back weeks later to find it again so I could credit the original poster, I could not find it. If someone knows or is the original poster, please let me know. I’d like to correct the record.
This is an insightful, detailed description on the finger method of drumming. Louis and Joe Morello were its two best known proponents. This is the best how-to description I’ve read or heard on the subject.
Also, I did not know Louie Bellson wrote columns for Down Beat magazine. I’m unable to find any info about his DB columns online.

About 20 years ago I found this article on microfiche in my university’s library, and I printed out a copy. I should have it somewhere in my stuff, if you’d like me to send you a copy of the second page (although it’s probably not as good quality as the first page that you posted).
