To help you practice everything you learn, there are some extra tracks which have been recorded for you to jam along with. Try out any of the riffs, licks, solos or rhythm parts in the book with these progressions. As you learn new things in the second half of the book, practice them with these Jam-along tracks. You should also practice improvising your own licks and solos. As well as this, you should play with other musicians as much as possible, as this will help to develop your playing and also put your licks in a musical context.
