"If someone has nothing more to ask to music than what he already knows... all the worse for him!" (Philip Ball - The Music Instinct: How Music works and why we can't do without it)
http://proglessons.blogspot.it/p/la-mia-vita-musicale.html, I'm an amateur drummer and I often play Prog, Fusion and Jazz music for training purpose.
1. "Covering and tributing a good band is the best way to become a good musician"
TRUE. As I before mentioned I always play some good track from Genesis, King Crimson, Gentle Giant, Yes, and so on during my trainings, for the same reason... BUT ALWAYS ON MY OWN or with friends, to check our improvements, not to propose it to an external audience!
2. "Today in Italy it's the easiest way to earn money with music"
ALMOST FALSE. The most of cover/tribute band musicians already have a good job and, on the other hand, they are not forced to avoid composing their own music and propose it (maybe often they don't feel able to do it?).
This obviously doesn't mean that they should play for free... even if sometimes they should deserve it!
3. "All jazz musicians are cover ones"
FALSE. Apart the most of jazz musicians ALWAYS compose music on their own, you cannot compare covers and tributes with standard jazz performances. The second ones involve a huge part of improvisation, leaving only the main theme for the recognition of the song.
If you go to a tribute (and often a cover) band concert, they play songs AS THE ORIGINAL. Sometimes there's a little part of interpretation in covers, but not so much, to avoid audience disapproval.
4. "Classical Music is always a tribute"
TRUE/FALSE. Surely you're not saying that performances don't change in intensity and interpretation among the Music Directors!
Furthermore in many cases you cannot reach the original versions played by the composer, because of the absence of recordings.
It's true that every performance is almost a tribute to great Music Composers of the past, but don't forget the musicians are Orchestra Professors and that reading the music sheets is often their only job!
I know some of them that also create music on their own... and it's not Classical Music after all... and they enjoy to play it so much!
Moreover... I've never heard of a group of classical musicians who identify themselves as "The Franz Liszt's tribute orchestra".
5. "It's what people want"
6. "It's the only way to listen to old (I say sometimes not so old) music classics nowadays"
Why mainly in Italy?
