Humility isn’t a word you would choose to use for anyone describing their tour as ‘Blues Giants’. For Tuesday’s Harmonie visitors it was very much a case of ‘put up or shut up’ as they say. In the event it was very much the former as past visitors Mike Zito and Albert Castiglia brought with them one of the strongest, bluesiest, bands to grace the stage in recent years. A spoonful of Blues at it’s electric best in fact.
