Hi Ken & Harvey, thought I'd throw in my thoughts. First, if two versions of this post appear please accept my apologies, I've just submitted one & it's vanished, so here goes again!
I think Neil Young is on the ball in the technology department, he's heavily promoting blu-ray as a format. The sound is vastly superior to cd & the picture to dvd. His album "Le Noise" was filmed as he recorded it, so buyers could either listen to it or watch it whilst listening etc.
With regard to revenue streams, I imagine that the record industry must be near to admitting defeat in that area. (Anyone in the industry feel free to shoot me down as this is just my opinion.) I base this theory on the low costs of buying music compared to the horrendous cost of concert ticket prices. Back in the early to mid 80's when I, as a teenager,was going to a lot of gigs, the average price of a ticket to see a successful band was approx £5. The cost of buying the album they were touring to promote was approx £4.50, in other words buying an album & going to a gig cost just about the same. Nowadays an average ticket is £30 - £45, & the album costs approx £10. And the "super gigs" are even worse. I saw Queen at Wembley Stadium in 1986, THE big gigs of that summer, & the tickets were £12.50, roughly 3 times the cost of the album they were promoting. Last year my neighbours went to see Bon Jovi do a big out door gig, £150 a ticket, 15 times the cost of the CD! (& they weren't the most expensive tickets!!). And Bon Jovi are not unique in this, the Stones, Elton, etc etc all have similar ticket options. I know there are exceptions, & that I'm generalising, but I can't help but think that things must have turned 180 degrees over the last 25 years & that touring, rather than record sales, is where the money is for many established acts.
Harvey, whilst I personally think that buying albums has never been cheaper in real terms, I agree with you 100% about the extra tracks racket. The one that makes my blood boil is when, as a fan, I dutifully buy a new album by an artist I follow when it's released only to see a "deluxe version" issued a few months later (usually in the run up to xmas) with the extra tracks on it! GRRR!
