in 2013 saw mark play 6 times, also saw eric Clapton and chris rea at bluesfest
most enegery on stage was chris rea!, dancing and spinning around ,and amost tripping of a guitar lead,and voice good as well
think claptons voice was the best out of the 3 and playing seems ok too,
but overall think knopflers concerts were the best out of the three, just that knopfler sound and his voice has never been great but goes with the music , think 2013 had way more energy than the 2010 concerts may of been due to his back in 2010
