You can get your band to be famous by having it play at different places. This includes local events, weddings and churches either for free or at a very small charge. Use this time to show what your best in thus, have your band sing vigorously. Ensure that you mention the band name as well as where you are from.
Play at charity fundraisers like fetes. Do u have a battle of the bands yearly competition where you live. All unknown bands perform in public. Do some free gigs at friends 21sts etc that may lead to paid bookings. Good luck
