Steve Neff is a wonderful sax player and has written a number of eBooks and other instructional material. “Best Minor II-V-I Patterns” consists of 80 Minor II-V-I patterns. Each pattern is four bars and includes the pattern in all 12 keys. The first measure is a ii7b5 chord. The second measure is a V7b9 followed by two measures of minor. I have finished playing through all of the patterns in one key. Learning all 80 patterns in all 12 keys will keep you busy for awhile. There are many nice patterns and I suggest that you add this book to your collection.
I have a post on this website entitled II-V-I Minor Long Sequence Backing Tracks that you can use with this book.
You can purchase the book at Neff Music
