Is anyone here still into live concerts these days?

I still go to live shows, but am doing less so because most of my favorite bands are a fragment of the original group.  I did catch U2 and The Eagles at the sphere.  What amazing shows and the most incredible venue ever.  165,000 (that's correct) speakers leads to pinpoint multidimensional sound-not the mono sound typical of standard venues.  On Hotel California, the chorus was sung by faces in the ceiling and the sound came from overhead.  Pretty cool. The picture show, though, is worth it alone.  Both bands had specialized 3-D video to accompany the music.  Like a Disney attraction, it doesn't matter where you sit, you get the same incredible in your face presentation.  The Sphere takes a concert to a whole other level.  If you haven't been, do yourselves a favor and go to at least one show there.  Absolutely incredible.

I also saw two nights of David Gilmour on the Luck and Strange tour at MSG.  Amazing.  David still puts on a great show and his new music is the best product I've heard from an aging classic rocker ever.  If you're a Gilmour fan, check out the latest offering.

Pop music concerts use amplified public address systems which have no better sound than modestly-priced audio gear in the home. This makes higher end audio pointless. 

In an opera or a concert hall, where all music is acoustic, you get a better idea of how to judge how well speakers, amplifiers, and sources need to sound to closely resemble what you hear live. 

If there is something special, such as a Mahler symphony, or operas by composers I like or who have written something new, I go. 

In choosing components, the effect of cables costing thousands of dollars or half-million-dollar turntables is comparable to the acoustic effect of the clothes you are wearing or where you are sitting.

@drbarney1 - PA technology has gotten immensely better over the decades; Just because you've not experienced a high-quality PA does not mean they do not exist. It's an extreme, but check out the Sphere in Vegas. But some bands like the Grateful Dead and Pink Floyd had excellent PA tech for many decades. Higher end audio is most assuredly NOT pointless to ME.
