Here are two examples from Metallica; the first one which could have been advertised a lot better:
I am sure that fans of Metallica were already aware of this, but buying two tickets for their tour next year I suddenly found myself in possession of two redemption codes. Each one could be handed in for the latest album.
As I didn’t know this before I bought the tickets, I just checked if I had been blind. It took some time to find it on the website, but finally I did. It is actually hidden behind a couple of clicks but it says
Every ticket purchased includes your choice of a standard physical* or a standard digital copy of Hardwired…To Self-Destruct.
We will send you a redemption code following purchase. Each unique code can only be used once to redeem a single copy of Hardwired…To Self-Destruct. If you already own a copy of Hardwired…To Self-Destruct please feel free to share with family, friends, colleagues etc. Full details of how you can gift the album will be given on the redemption page reached via a link we will send you.
Enjoy the show!
*Physical copies carry a postage and packing charge.
I would probably have advertised this a lot. But I am not complaining, because I just got two digital copies and I can give them to other people if I want. I now feel that the tickets had greater value than before.
The second example is that you can buy and download the recording of any concert. So, when we in 2012 went and saw Metallica in Horsens, we could afterwards go home and buy the recording from that night online.
I am guessing they haven’t done a lot of remixing afterwards and the recording is pretty raw. For a fan this is a great offer and adds yet more value to experience of going to a concert.
