I have a lot of friends that are in local bands.   As any musician can tell you it's almost impossible to get airplay on the hometown radio stations.
 
So how do they get additional publicity and promotion?

By getting involved in charitable events. 

A lot of the big fundraisers are co-sponsored by television and radio stations.  When the stations talk about the event they mention the bands.   The bands get a lot of goodwill in the community and a ton of free publicity.  

It helps them get more bookings for top dollar.

There are plenty of ways to be noticed in the marketplace.   Don't be afraid to try new methods.  The more people know about you the more likely they'll be able to buy from you.
