Citat:
I really do not know much myself. If you google you may find a lot: David and Linda have the same father as Avicii. But they are 15-20 years older than Avicii and grew up with their mother. So there it might be just seeing each other once in a while.
About Anton. He grew up with his mother mostly, although moved out from family home very early. The age difference to Avicii is 12 years. So if I add it up, they probably grew up together until Avicii was aged between 6-8 years old? Probably not longer as Avicii and his parents moved to Skåne (south of Sweden) where Avicii attended school for a year (about 11 years old).
I read on-line an article about the fact that Avicii announced his stop of touring and the reaction from Anton (Aftonbladet 29 mars 2016) Anton said he never talk to Avicii, yet he know Avicii talks frequently to his parents. Anton also said about Avicii: He never answers as I call, the little prick (free translation from "Han svarar aldrig när jag ringer, det lilla aset!". On Antons instagram (akorberg) he does not have even one picture of his half brother Avicii or the mother Anki. He do have close connection with his father though.
I also heard thru the grapewine from friends of him, that they was hanging out in Tims own little rental one-room apartment in the city from the beginning as he went to the gymnasium, playing computer games and making music 24/7. That means that Tim moved out already when he was a teenager, that is very unusual in Stockholm/Sweden.
With this said. I do think Avicii was too young to have a close relationship with his half brothers and sisters growing up due to the age difference and that most of them grew up in another household. It do seem though that Avicii and halfsister Linda talked and cared about each others. About Anton, also a huge age difference and by the like of it with Antons interviews and so forth, very bad connection even for halfbrothers.
I do think Avicii did have contact with his parents. His father is head of Avicii all companies too!
