We are being released by a record company in Italy on an Iron Maiden Tribute album and a Metallica Tribute album. Since we know and people have acknowledged that our music is good, can you give us suggestions on how to go about it from here. If people have acknowledged that your music is good, you're getting some encouragement. It might not seem like a lot, but there are people who enjoy what you're doing. Changes are that they have friends who will enjoy it also.
People go where their friends are and where the event is.
A lot of bands go against the grain. You mentioned two of them in your question. Just concentrate on building your fanbase. Do it one at a time if you have to. Those people will add up and the whole thing will snowball.
