Royal blood released an EP, but an album followed.
John Mayer is doing it with great success
Skid Row are doing it
The Virginmarys did it
Toby Jepson (Little Angels) did it
There are loads of more, but I can't be bothered to Google it, you can do that for yourself...
The majority of smaller bands that are still building a following do it....
I realise that you may not have heard of all of these artists, but that isn't the point. Most people haven't heard of RSO...essentially this is a debut album. They still need to build their own following...
You are used to the major label bands....remember this project is going to be self financed or a small label not a major, it doesn't work the same.
Here's some interesting articles on it. The point is null and void though, as RSO are releasing an album after 2 EPs...

Going forward less and less bands are going to be releasing full albums. Younger kids just don't buy albums. The older punters (and bands) won't be around forever
