Oi oi!! We got someone from Essex! Love the name of the band too 😃
Welcome to Hive, quite a few musicians around here which is great! You can find the music community page here and be sure to use the #musicforlife tag when you share your music too!
It sounds like you have a couple of gurus to help you get started but if you want a little reading material, I summarised the basics of account set-up etc here and have an evergreen list of all the different communities/topics here!
