I'm not quite sure if this is the right place, but here goes....
Over the past couple of years I've been working on a book/CD designed to teach a traditional approach to playing backup guitar for old-time country music. It's finally done, and the feedback from folks who've bought it (at Clifftop, at Battleground, via mail or via PayPal) has been really positive.
The concept behind the book is to learn backup guitar by listening to and imitating some of the very best backup guitar players of the 1920s and 1930s. In addition to a few chapters' worth of text, the book includes tablature for 28 tunes, transcribed from 78 rpm records. The tab is for the chords, bass notes, and runs played by guitar players such as Luches Kessinger, Asa Martin, Edgar Boaz, and Roy Harvey. The CD includes 123 mp3 files, and there are at least 4 versions of each tune from the 78 rpm records, all pitch-corrected. The 4 versions are at full speed, 2/3-, 1/2-, and 1/3-speed, so that the student can learn by playing along, at a comfortable pace, with the original performances.
What most folks probably haven't thought about much is that the mp3 files on the CD are ideal for learning and practicing tunes on the fiddle. The slowed-down versions are terrific for catching nuances of these classic tunes, played by fiddlers such as Clark Kessinger, Doc Roberts, John Dykes, and a number of others.
There's additional information at my new website (http://www.L-century.com), including feedback and testimonials from a bunch of folks who've already got the book, including some who should be pretty well-known among this crowd. The book (102 pages) and CD are sold as a package, for $24.99 plus shipping.
