The book titled Banjo Camp! Learning, Picking, & Jamming with Bluegrass and Old-Time Greats has been out for about a year. It's a soft-cover, full color, 152 page publication that includes a CD. The reason I'm mentioning it now is that I just got around to buying a copy. The other reason is that I'm in it! You can find me on page 38, which is in the section talking about Kaufman Kamp, where I've taught for the last six years.
The general idea behind the book (which I admit I haven't read all of yet) is "banjo camp between two paper covers." It combines instruction, visits to various banjo camps around the country, student testimonials, plenty of pictures, and music and examples on the CD at the end. In my three paragraphs I talk about slow jams and their value to students at all levels.
The author, Zhenya Gene Senyak, writes from the perspective of a typical banjo camp student---adults who picked up the instrument later in life and now have the time and money to come to events like camps to develop their playing. The book contains lots of information, but mostly it's just fun to read something by and about other who are interested in the same thing we're all interested in: learning to play the banjo!
