It's already been done!
There is already a very comprehensive concert list maintained by Duncan Glenday at Progressive Ears. It's really something that I don't think could be improved upon all too much and is fairly comprehensive and frequently updated.

What we REALLY need on AM or elsewhere is a much more comprehensive "new release" schedule than currently exists to my knowledge. Generally the ones that are around are very limited in scope.
