Avid fans of music or musicians themselves would want to keep themselves occupied especially during the school vacations. Organizing a local concert is one thing that would both quench their thirst for music as well as be an income generating activity for them. Parks as a location is a very inexpensive venue to host these concerts and they are not difficult to manage.
Always remember to ask permission from your local government to allow you to have concert in the park. Submit a very convincing written letter to them stating your purpose and how the community would benefit from this activity. Follow it up every now and then since these people have too much on their plates.
Of course, for it to be a success you have to invite indie artists who are willing to play for free or just a small amount as long as their band would get recognition. The school is one place to look for them since most of them are just garage bands and would like to play for a crowd. You can also invite relatively famous bands from other places through social media and word of mouth.

Have a Bit of Everything
For the song selection, make it a relaxing time for your audience. Make sure that you have songs for the younger generations as well as the older ones. Do not overflow them with all metal or all rap songs as this will be an avenue for them to bond and you would want them to come back.
Aside from the concert itself, you can have friends sell stuff on booths and income generating activity.
