Kung rock, puro rock lang . You should be open to all types of music para magkaroon ng diversity yung music n'yo . You should also love what you do because if you do, your work will have depth and soul. You shouldn't always do things by the book. As long as you're happy with your music, you can do what you want.
Music is the important thing.
Love is enough. If you're happy with it, everything will happen. A band should know how to listen to each other especially if it's a live performance. You should learn how to play with your bandmates. You learn to adjust to your bandmates.
