The 38-year-old was formerly one half of Scottish pop group Arab Strap and is now in a duo with instrumentalist and composer Bill Wells.
They will be performing songs from their recent album, Everything's Getting Older, at the Paisley Arts Centre.
Aidan has lived in Glasgow's South side for the last 12 years and met Bill in a pub in 2002.
"I ended up sitting in a pub with him once because we had mutual friends. Apparently before we had even started the conversation I asked him to play a record with me.
"I knew his music and he knew mine so we just started working together through that."
Aidan, who partnered Malcolm Middleton in indie-rock band Arab Strap from 1996 to 2006, said he got a real buzz from working with Bill.
He said: "I do stuff on my own, but I get a better kick out of working with other people. I enjoy creating things with other folk.
"There is a confidence you have when you are part of a unit. Every time I have released a record on my own I am probably much more anxious about it – you are just not sure whether or not what you are doing is right at times.
"But when you have got other people to work off and you are part of a band, you feel a strong bond."
Wells, who is renowned for his jazz music, may seem a strange partner for Aidan, an indie-rock man.
Wells is leader of the Bill Wells Octet and has worked with the likes of The Pastels and Isobel Campbell, the singer, cellist and composer who was formerly in the group Belle & Sebastian.
But Aidan said he and Bill get a lot from each other.
"Bill is often described as a jazz musician and he does use the instruments of jazz, but I don't think he wants to make jazz music as such.
"But there is a jazz element to this record, which is something I never thought I would have said 15 years ago.
"I am happy to try lots of different things, there are no rules about these things.
"As long as you find like-minded people it does not really matter what they play or how they sound as long as you understand each other."
Featuring tracks like Let's Stop Here and Cages, the album is packed with jazz-infested love songs the pair wrote together.
"Bill would give me two or three CDs full of different tunes and the ones that I engaged with I would pick out. Then I would put lyrics I already had to it or write around it the tune.
"Sometimes, I just listen to something and try and think what it makes me think of and work round that."
He said he could not describe the music they produced. "It's reflective", was all he could say.
He added: "When I was at school I always believed in the things the teachers say about 'Always write about what you know.'
"Everything I write is very autobiographical. It used to be I got my ideas from hangovers and things that perhaps should not have happened the night before."
Glasgow Jubilee, a song on the album, is based on an 20th century play called La Ronde and updated to fit into modern-day Glasgow.
"Everybody is horrible in that one, that is what I like about it. I wrote myself into it and made sure I was a right idiot as well, so I am quite proud of that one."
The album was supposed to be a one-off collaboration, but Aidan said there may be more to come.
"The plan was it was going to be the only one, but I think we might do a new one, I don't know.
"It didn't take us eight years to make the record, but it did take eight years to finally getting round to booking the studio time to do it.
"We talked and talked about it for years and just always had other things to do, but there is no rush to do these things so I expect there will be more."
The Paisley gig is a preview of their Europe tour, starting in Edinburgh in a couple of weeks.
The pair played at Paisley Underground last year.
Aidan said: "The Arts Centre is a lovely wee venue. we are going to do the set as more of a quiet thing, a bit stripped back and a bit more gentle. It is a nice wee room and is great for intimate things.
"There will be a few extra songs not on the album, but we will certainly play as many as we can.
"You forget sometimes that you use a bit of studio magic, so some of them might be around in a different form because sometimes songs are better live if you play them differently."
l Bill Wells and Aidan Moffat will be at the Paisley Arts Centre, Friday, 8pm. Tickets, £12 (£10 concessions). 0141 887 1010.
