We really don't know exactly where Pan Amsterdam comes from. He was found on the coast of Miami Florida in a state of apparent amnesia. However, we've been able to compile some information on him and are very close to connecting some dots...
When Pan Amsterdam washed up on the coast, he was wearing an oversized black velvet jacket on which, a cigarette burn. Black jeans and two different coloured Church Socks. Further along the coast, we found a trumpet case WITH a trumpet inside of it. In the case's side zipper, we found a mouthpiece and valve oil for the horn along with an external hard drive with tape on it. Written on the tape were the words, "Elevator Music".
Pan Amsterdam must have been unconscious on the coast 22hrs before he was discovered by none other than rock icon and "The Godfather of Punk", Iggy Pop. When Iggy revived Pan Am, his first words, recalled by Iggy were, "Washgood, put me on Plus One". He went on to say his name was Pan Amsterdam and even though "Calvin got a job", he didn't want the job Calvin had.
Nonetheless, Pan Am is clearly from the U.S.A because he has a North Eastern American accent. Although we haven't been able to pinpoint it, the accent sounds like a cross between Brooklyn, Manhattan, or Jersey.
