i have been studying blues guitar for the last 2 years now. i've a number of books on the subject. i've progressed reasonably working with them.
then i got this book. learnt a couple of songs. and my playing has simply jumped a notch!
yeah because i'm playing what i want to play - being a huge clapton fan (bluesbreakers, cream etc). plus clapton is playing in such ways i never encountered in the tutorial books. his chops are simpler but much more effective. but some of his runs are quite difficult - not the mere playing of the notes, but the effect created by such.
i'm never going to play what's in the tutorial books anywhere - but this is what i want to play and it is such great fun doing it.
i can't comment too much on the accuracy of the tab - it sounds ok - trying to figure out the notes with the actual solos is itself quite a job - i recorded all the solos of this album in triplicate on a tape to use them as a reference. but guess it will get easier as i progress.
it would be very helpful if you know atleast some basic blues - the 12 bar, the pentatonics etc. needless to say, as with all blues learning, one should focus on the tonic (1st), the dominant (4th) and sub-dominant (5th) notes and the way they are manipulated to create the blues effect.
if you want to play like clapton get this.
btw i wish somebody would publish similar tabs of the music of the great peter green - his album with mayall 'a hard road' and his early fleetwood mac material as well.
