"John Racina's fast-paced book for musicians of all levels, is designed to expedite the development of an effective blues-based jazz performance vocabulary.  I especially like the book's versatility; it's useful as a method for progressive study, as a jazz resource, or as a stockpile of ideas for a Saturday night gig. Racina knows what really works on the bandstand, and he articulates clearly the practical information acquired during his long career as a teacher and professional musician.  I highly recommend Blues Riffs as a valuable course of study for both individual and class instruction."
Neil Slater, Director, ~ One-O' Clock Lab Band Chair, Division of Jazz Studies University of North Texas, Denton, TX  

"John Racina's books are a no-nonsense approach to jazz education. I have used them in private lessons, in classroom teaching and in my own practice sessions. They work very well for young, intermediate and advanced students of jazz. I recommend these books to anyone who wants to improve their playing in the areas of jazz improvisation and sight reading"
Mike Vax, ~~ Yamaha Performing Artist

"John Racina has presented some excellent information and musical examples which are the result of his many years of success in the professional music world.  Each performer who utilizes this material will undoubtedly gain much to help in future performances.  I recommend this book without reservation."
Leon Breeden, Professor Emeritus University of North Texas, Denton, Texas

"John Racina is an experienced musician who has a lot to offer in his teaching and writing about jazz.  These blues etudes and heads are heavily steeped in the jazz tradition and offer an aspiring player a huge amount of good vocabulary.  John's book, "Blues Etudes, Patterns and More", is filled with swinging ideas that are fun to play and tie in nicely with the Jamey Aebersold series of play-a-long recordings"
