Thinking about it...
Live music was the catalyst for a lot of people in the last century.
Those that sat through some horrendous support bands were sometimes rewarded with an absolute gem. I'm sure I've mentioned this before, but I went to see John Martyn at Sadlers Wells. He had not one, but two support acts, so you'd think maybe a trip to The Shakespeare's Head across the road was quite in order (which is probably where you'd find him, pre-gig). Tanita Takiram was more or less boo'ed off stage for her curled up pork sandwiches. But then on comes another solo guitarist, no fanfare, no introduction, no waiting for hush to descend, she just started to play and after a few bars we were entranced. People in the audience were whispering "who is this?" and very few people knew it was Tracy Chapman. History in the making, as it were. How any AI app can connect Martyn and Chapman would be anyone's guess, but I suspect a lot of people who saw Martyn on that tour still appreciate Tracy Chapman too. In those days it was probably agents ringing round "I need someone, anyone to support a Glaswegian folk singer at a gig at Sadlers Wells."
A lot of the so-called rock radio shows would get their inspiration from the many pub rock venues (Red Cow, Golden Lion, Hope & Anchor, etc.). I believe that's how e.g., Dire Straits, The Police and Tom Robinson found fame. Who remembers bands such as (and I quote) "They Shoot Horses Don't They?" I was into a band called Bethnal who did a ground-breaking (literally) version of Baba O'Reilly featuring a violin solo (when played live) which was streets ahead of the original (IMHO). Doesn't sound much on YouTube... in fact, please don't! But in the pub, or Hammersmith Odeon (which they did get to play) you can truly immerse yourself in the atmosphere.
One of the problems of today is "Listener's Digest". Who listens to an album in sequence from first to last track these days? I think this is one of Neil Young's beefs for temporarily, at least, pulling his back catalogue off music sites. Digressing slightly: who has watched The Italian Job from start to finish? Most people just want to see the chase, and once you've picked that out of the highlights, why bother to watch the whole thing from the beginning? This has been going on for years with classical music, but rock is arguably now the same.
A lot of the true rock classics don't fit into a standard single slot "Stairway to Heaven" and "Layla" immediately come to mind. Maybe why Mountain's "Nantucket Sleighride" rarely got air play.
Sorry, now where are my meds?
