Medical treatment against cancer is long and difficult, in many cases that's what pushes children to give up. It's scientifically proven that music generates a positive reaction in their body, which helps them keep fighting against the disease. With the collaboration of the Hospital Civil de Guadalajara, and Sello Rojo, we formed a music band integrated by children patients with the purpose of fighting the disease with music. Each view of the video on Youtube translated into a monetary donation, the total amount of money collected was destined to buy a completely new machine for the hospital, that machine is now working and it detects cancer in a faster way.
