Lee Konitz, who turns 80 in October, ambled on stage last night at New York’s Zankel Hall, blew a note, asked his audience to hum it, then, as we all hummed it continuously like a dirge, he blew over it on his alto sax, an improvised solo, darting and weaving, choppy then breezy, sifting changes, shifting rhythms, and all so very cool. It lasted five minutes, it probably could have gone much longer. Then two old pals, bassist Steve Swallow and drummer Paul Motian, joined him, and they played standards. Tenor saxophonist Joe Lovano came out to trade fours and eights. They all left, and on came a string quartet, which played ballads and Debussy, Konitz cruising over the sweet strings in his signature airy tone, with its syncopated cadences and wry, insouciant swing.

Conn and Hal's Iggulden's <A HREF="http://www.washingtonpost.com/wp-dyn/content/article/2007/06/22/AR20070… Dangerous Book for Boys</I></A> has been on my must-read list since it was published here in the States, but Conn's lovely essay, "In Praise of Skinned Knees and Grubby Faces," has catapulted it to the top of my list.
