This server allows users to find out about the latest musical events worldwide. Users can implement a search via HTML forms, specifying dates, musical genres, geographical areas and individual artists. The server will return with a list of known events that match these criteria. In addition, users can add information on events that the Musi-Cal database doesn't already know about. This server also allows geographic distance searching as well, so users are capable of searching for all musical events within 10 miles of New York, for example.
