Stevie Wonder in Sydney

Last night I saw Stevie Wonder live at the Acer Arena in Sydney. To put it simply he is an absolute genius. He has written so many huge songs which have appealed across platforms in the pop world and also into the jazz world. His voice was as good as it has ever been - amazing, and effortless.
He really played to muso fans last night too which was great - he didn't just play a pop concert. He started off playing Miles Davis "All Blues" on the harmonica. Not a predictable way to start and absolutely brilliant. He also played some other jazz numbers through the night - Spain, and Giant Steps, and then all the funk classics, plus the crowd pleaser pop tunes. But even they are brilliant works of art.
There were 15 people on stage - 2 percussionists, drummer, 2 keyboardists, 2 guitarists, bass, 4 bvs, horns, and Stevie. Huge.
OK now here is my gripe. Why in this day and age can no one install a sound system in a large venue that sounds good? We pay all this money for concerts that sound like crap. There was no clarity in the bass at all. The whole night it was just a huge rumble, so all those funk tunes which are so reliant on the bass line were just mush. And I don't believe it was the fault of the engineer. I think those venues are just rubbish. Like Sydney Entertainment Centre. Everything sounds awfull. Surely the artists would like to think that they sound good out the front. And as a bass player I know that bass players like to be heard - especially when they are playing really complicated lines. All you hear is the sub and no clarity. Drives me nuts. And it really detracts from the enjoyment of the concert.
Anyway Stevie is awesome.
