Well, I wanna know what happens to people like, once the album is completed what happens next? does the album get shipped over to a million or billion stores in the UK? USA? Germany? Italy? Etc?? what happens from there? what if people buy your album? would it take long for you just to blow up and become big news or will it be harder then that?
Answer on What happens with people that go to a london or an english studio and make an album for the first time?
If you have a contract with a major music label, like Universal etc. then they will have all the details in your contract. Usually first time artists will only be available in their home country, in this case the UK. If the record company believes one of your songs will become a hit and popular in other countries they might contact their headquarters for example in Germany and Italy, and maybe try to get it on the countries main radio stations. this process will however take a couple of months, unless it is a real big hit.
If you have a contract with an independent music label, this is obviously going to be downscaled to the city you are in, and if it is successful, possibly to other major cities like London, Birmingham or Manchester etc.
If you have no contract and paid a recording studio to record your music, you will simply receive your album and you will have to do everything yourself!
