"Unfortunately, the reality is Jazz is percieved as an 'old' music that's best days happened decades ago. Not only here, I've even found this mindset on jazzsites!"
You mean just like classical music? Show me the 'new' mozart, bach... the 'new' Mingus, cannonball, armstrong et al
It could be that Jazz, the REAL stuff, has just about run it's course. Just like classical. There are some modern composers out there, but the repertoire is still almost totally pre 2oth century, with damn few exceptions. The same can be said of the Blues, R&B, rock & roll, country and gospel. Their most creative era is behind them. If this were not true, today's opera would not be just the tried and true in modern wardrobes. There would not be 302 different recordings of Beethoven's syms. We would all be listening to the 21st century beethoven, the new howlin'wolf, the latest elvis, where is the modern motown? ... you get the drift. The golden age in pop and jazz and classical and gospel and r&b and country IS OVER!! The only thing we have left are reissues that hopefully have improved sound quality. The new music is not saying anything. Metal and rap were never music to start with. BTW, rock & roll and Rock, are not the same thing, so, the stones and several other social security aged rockers are still active because there are no replacements. Same holds true for Jazz. Sadly.
