“100 years of Blues & 60 minutes to play it”. That’s how Edinburgh Blues band The Blueswater describe their musical mission at the yearly Edinburgh Festival. Certainly, they play at an often frantic pace that suggests they might even cover all that ground in an hour. They even got an extra 30 minutes on top at Kult 41 on Sunday and sneaked in half the band for the support slot to shoe-horn in as much premium RnB as any sane, blues-loving human could hope for. Certainly, if you didn’t know by 10pm what the Blues was all about, then quite frankly, Jack – you dead!
