A few years back I made a hobby project like this -- it scraped the website of the local free weekly paper (since they have pretty much every concert listing, large and small) and then did a youtube search on band names so you'd see an embedded video or two for each show.

I think most larger cities (and smaller cities if they have a large university) have such a newspaper (e.g. Village Voice in NYC, Willamette Week in PDX, The Mercury in Seattle, etc)

Maybe it's better in the states, but where I live the papers don't come close to being a complete listing. They will have the major stuff, and some of the smaller shows too - but a large part is still missing. And it's not a small city - 2 mln people, capital, and quite an active music and culture scene.
