For any aspiring banjo picker this book is essential reading. I enjoyed the technical information on instrument set-up as well as the indepth interviews with so many of the people who made bluegrass music what it is today.
It goes beyond the "ten steps to good playing" approach by showing, in great detail, how so many great players think about, practice, prepare for, developed and performed their craft.
Read it from cover to cover then keep it handy as a reference work - excellent.
