Excuse my ignorance, but what is exactly a "360 deal" (could you elaborate on what you said in your previous post please) ?
Yes, no problem.
In the old days, a record label would simply make money from an artist by taking the bulk of the money from every record sold (be it CDs, vinyl etc...).
Typically, the artist would get a royalty rate much less than the label would make from the album (even the very biggest artists like Michael Jackson would earn less than half of what the label would make from it's wholesale price). Of course, this was somewhat fair as the label would be responsible for a great amount of the associated costs of the record.
However, the label would not take anything from the artists earnings where the likes of endorsements, touring and merchandise was concerned.
But then the music industry changed. Some say it has died, but that is not true. The music industry is bigger than ever - it's just that the ratio of revenue has dramatically changed with revenue from actual music sales declining but revenue from related endorsements and touring rapidly increasing.
In a nutshell, bands used to tour to promote a record but now they release a record to promote a tour - at least economically speaking.
So, as the industry changed, record labels and artists changed the way they work with each other. Both still parties still need each other, but it is not sustainable for a record label to survive off record sales alone and it is not possible for an artist to get an album out to the masses without a record label (generally speaking). So, a 360 deal sees both parties (label and artist) work out a deal where all revenue from all sources is shared between themselves. So, now a record label will get a share of the artists touring revenue, merchandise sales and endorsements etc....
This allows record labels to still have confidence in investing in the recorded music side of things knowing that even if the actual revenue from music sales is down, they can recoup on other sources of related revenue.
Madonna was one of the first to follow this model, and Maiden were at the forefront too.
