Came up from busking through homelessness and catastrophic illness with my loud booming voice, my aggressive strumming, and my cornet.
I found that when I had made enough money to buy myself an amp, my earnings doubled. Along the way, I keep adding to my kit, using a looper now to lay down a guitar track I can play the trumpet over.
It's not about drowning other's out, it's about creating the best music and sound that you can in order to make as much as you can. So you can keep a roof over your head, and food in your belly.
