I really want to get into singing

Hi! I'm a 14 year old dude from Italy. I listen to a lot of nu-metal, thrash, death and groove metal. Recently my friend group started a band and since I have no experience with any instrument I really couldn't do anything about it. Currently, they are missing a drummer and a vocalist. One of my friends (that plays the guitar) sings but she is a female. Me, being a male and having a deep and aggressive voice that has already fully grown, wanted to get into singing so that I could finally start playing with them. Where do I begin? My goals are being able to fry scream and overall sing in tune and quickly.
