Blue Rockklassiker just .... for more advanced bass, the book is probably related not sophisticated enough for newcomers and career changers already. Each title is recorded both as a complete package or as Jamtrack without Bass. The production sounds very good and as far as I can tell, the bass lines are very close to the original and contains the complete transcription for each the entire piece, including fills and variations. Crossbreed songs like "The Thrill Is Gone" alternate with quite sophisticated, such as "Pride And Joy", here let the high pace and wide stretches over four frets boredom!
It's fun to jam with these play-alongs and is money well spent!
