Last week, my lady Lisa sent me a link to a very cool website called harlem.org, which invites viewers to “explore jazz history through one photograph.”

Now, the photo in question, taken by Esquire camera man Art Kane, is one I had seen before, and is in fact quite famous. Featuring a veritable who’s who of jazz history, all gathered together on the steps and sidewalk outside an apartment in Harlem, the picture is utterly remarkable. Count Basie, Lester Young, Coleman Hawkins, Dizzie Gillespie, Marian McPartland, Milt Hinton, Mary Lou Williams, Thelonius Monk, Sonny Rollins, Maxine Sullivan, Stuff Smith, Oscar Pettiford…all there, along with many others, fifty-seven in all. The patriarchs and the young lions, side by side.

Still more amazing, however, is how harlem.org has utilized this photo to give you quick, biographical insights into everyone who appears in it. Just mouse over the photo to a general area of interest, click, and that section of the photo is enlarged. Now mouse one by one over the musicians in the enlargement and their names appear in a pop-up balloon. And here’s where it gets good: when you click on a particular musician, a larger window pops up containing a photo and information about him or her.

What I’ve described is just a thumbnail sketch of what the site has to offer. If you’re at all interested in the history of jazz, this website is a must. It’s worth visiting just to see the photo alone, but I promise you, you’ll find much more of value besides.
