Scott Dirks Interesting Blues and Harp page. Scott Dirks is a good harp player and a Little Walter historian. I know of him from his efforts to mark Little Walter's Grave. He was kind enough to make some very good comments about the content on these pages.
Jake's Page Jake's a good Harp player and a good friend.

"Brian Reeves" - Under construction, but interesting links.

Here is a little something to drool over.

These two pics are from a vendors table at a recent guitar show. It took two shots to get all of the mics! You can see old Astatics, Shures, Turners and dozens of other vintage mics. You can see the prices taped to a few of them.

I had the negatives transferred to Photo CD and then used Paint Shop to convert to JPG. I used various tools to paint the background blue. The original image was 2.2 meg. I got it down to about 60k each with 10 percent JPG Lossy compression. If you download these there is enough detail that you can zoom in to about 4-1 and get good results.

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.

Playing "Help-Me" In the Style of Sonny Boy Williamson II: A step by step, note for note analysis of some of Sonny Boy's Signature Riffs

I also write Science Fiction, so you can sample some of my best stories. Also available in Kindle format.

I began collecting data about the microphones used by blue harp players before there was an internet. I began organizing it into in the late 1990s. I accumulated more stuff than I remember. This is some of it.
