Some of these posts bring back many happy memories. Curtis Mayfield at Dingwalls, particularly. It was awe-inspiring to be in the same small room as a legend. Ditto when Sam Dees played there (although seeing SD live was always quite problematic for me, as I always got the impression he detested performing live). Saw Al Green at Hammersmith Odeon in the early to mid 90s, and he was everything you could expect him to be, a wonderful vocal talent and a master showman with tons of natural charisma. Anita Baker, too, at the same venue on her first visit to Britain in the 80s was a phenomenally intense performer, far, far removed from her coffee-table incarnation of later years. I can still hear her earth-shattering rendition of You Got To Feel The Need In Me which genuinely thrilled and moved.
Mark Bicknell mentions Otis Clay and I must state that he is pretty much the last of a dying breed, a straight down the line, all action, no-frills, blue-collar, real soul man, and an absolutely dynamite vocalist with a fantastic grasp of the dynamics of live performance. Seeing him you really could be transported to his roots in the hell-fire gospel tradition. Quite simply, he's awesome and I would urge anyone who can to see him while you still have the chance. Andy Dyson made the point here a few months ago that many of the soul greats are now operating on half-power due to advancing years, but went on to say this is not the case with OC. How true that is.
