So try find a bar or any other public place which will allow to show your talent. Try also to go to local radios to see if they’re interested in interviewing local talents.
An example of some famous artist who managed to get known through local radio is Ludacris. He started as a DJ on a Atlanta radio. With that job he met a lot of insiders who told him about the music industry secrets. It was a lot easier for him to record a popular CD with all his connections.
You can also try to work for a local music festival. Music festival organizers are always working for volunteers. If you manage to find a job there you will meet a lot of people who are involved in the music industry.
