JOESEF is standing in his flat in Glasgow's east end surrounded by polystyrene balls from a burst bean bag. "I had a party at the weekend and I'm now trying to clean up the aftermath. It looks like a warzone" he tells me.

Joesef is the most exciting musical export to spring from Garthamlock, the housing estate just behind The Fort in Easterhouse, and it is no wonder that he's been enjoying his newfound success.

Springing from the ether as a seemingly wholly formed artist, he sold out his first King Tut's gig without having officially released any music. Two more shows and an EP, Play Me Something Nice, later and it was announced last week that he will support Loyle Carner on his tour this month and will headline SWG3 on the eve of Christmas Eve.

"I only got into music two years ago. I went to an open mic night and my pal was the guitar player. I was drunk and I said I'd sing a song and I sang California Dreaming. He didn’t realise I could sing. A year later I started writing tunes and was going through a rough time. My first relationship broke down and I wrote about that and how I felt and here we are."

This elusive artist has been making waves all across the country in the last year, including making an appearance in Miss Vogue, which commented on his 'thick Glaswegian accent'.

"I feel like there was a language barrier between me and the lassie. When I picked up the phone she said she didn’t expect me to sound like that. She thought I'd be uber cool, soft-spoken. In reality I sounded like a tramp.

"She was really nice though. I don’t think I'd be as popular if I sung how I spoke. I don’t really try and put an accent on, it just comes out like that."

With comparisons to both Lewis Capaldi and Amy Winehouse, there is something refreshing about speaking to an artist who is willing to bare his heart and also make a joke about himself (it should also be pointed out the only other artist to have sold out King Tut's without releasing any music was also Capaldi).

It's one of the reasons that Joesef is on the up: that fresh brand of Scottish 'sad boi' music that listeners from outside Scotland are so mysteriously attracted to. Besides having the gift of the gab, a big part of his appeal is singing about his relationships with men as well as women.

"I wasn't a part of the Glasgow music scene, which I think worked to my advantage. I plopped in without knowing anyone and people were wondering who this guy was who just burst out and started playing gigs.

"When I grew up there weren't really scheme boys singing about kissing other boys. I think if anyone can kind of relate to that and feel more comfortable about it through my music then that’s class.

"There is a lot of emphasis on sexuality but if you just focus on it too much it becomes a bigger thing but really, who really cares who you're sh*****g?" "Newspapers?" I suggest. "I knew you'd say that!"

At least I can say I made this 'sad boi' laugh.

Joesef has a low-fi, bedroom-produced jazz sound that we've been hearing in the underground legions of budding musicians who simply don't have the money to make fully-scaled professional outputs.

"It's amazing what you can make when you have f**k all," he laughs. It's the classic Glasgow element to a character – thawing out the potential for a chip on one's shoulder with good humour, and a warm laugh. There is, of course, always a reluctance to be forthcoming with the potentially uncool – no one wants to be a sack. Joesef says he loved jazz but always in secret.

"When I was younger everyone was listening to GBX, not Chet Baker. I only started singing because I wanted to go on a school trip and couldn't play an instrument."

"It wasn’t a conscious effort to be a singer but I love doing it. Where I'm from nobody does anything like this, everybody is a workie or a joiner or something like that."

One gets the sense that Joesef can't believe his luck, whilst taking it in his stride.

"Before, I worked as a bartender, just floated about. I was always happy but it was a bit of a cycle of boozing and working, working and boozing. I would have been fine but getting into music has made me more ambitious. I think sometimes you have to give yourself a shake. I have more to offer. I think it’s probably given me a better future."

Joesef supports Loyle Carner in SWG3 on October 30 and headlines on December 23. His EP Play Me Something Nice is out now.
