I’ve spent much of the past week mentally re-living Ahmad Jamal’s performance at the Barbican– easily one of the most enthralling nights I’ve experienced in a concert hall.  Is there a hipper octogenarian anywhere on the planet? I gave the show five stars in the Times [£]; the FT and Guardian were just as enthusiastic. The one tune I expected to hear was his timeless hit “Poinciana”, but for the first time I can remember, he chose not to play it. Thanks to the wonders of YouTube, though, it’s possible to eavesdrop on this 2012 version from the Olympia in Paris. For some reason, the title is given as “This is the Life”, but there’s no mistaking that melody.
