I was over at the Bowery Presents website the other day (for those not in the area, they're the promoters of a vast majority of cool club shows in NYC) to check show times and I noticed something I hadn't before in the upper right hand corner of the page: iCal and Google Calendar links. So now, with a single click, I can superimpose every show they're putting on in the city over my Google Calendar (which is, in spite of my efforts to prevent it from becoming so, a now-indespensable life tool).
Granted, there's nothing life changing here, but it's just one more nice touch on a concert promoter's website full of nice touches, and some band sites could certainly learn from the simple utility therein. There's a Last.fm station playing soon-to-perform artists, a regular podcast promoting events, an email list, and the calendar links. The scramble not to be caught flat-footed by having no idea that your favorite band is in town just got a little less frustrating.
