"It's basically me and the whole studio on stage, which is getting to be a real pain in the ass," says Marks on his live shows as Banco De Gaia. "It's taking longer and longer to set up and there's more and more things to potentially go wrong. Cables to break, and stuff. But we rely a lot on lighting, I have a lot of lights and films, videos, that kind of thing. One person standing on stage with a bunch of keyboards isn't really the most interesting thing to watch. So we try to create a bit more of a visual spectacle."

Marks runs all the sequences live on stage, remixing them live and playing keyboard lines over them. While many performers are afraid to bring a computer on stage, Marks sees using his Mac as the only way to go.

"I have had problems, but it basically wasn't an issue for me," he explains. "Because of the way I write and work, I couldn't really use a hardware sequencer. I have to use a computer because I have so many tracks running at the same time. It has to be software based. That's why I got the laptop, because I figure a computer that was designed to be carried about and moved about would be fairly rugged. The only problem I've really had has been compatibility, because I've got a Power Mac in the studio and then the laptop for live and there's timing problems between the two. They seem to have a very slightly different idea of what a second it, and I haven't really worked out why this is. I've spent hours talking to the software people trying to work out why this is, and they can't work it out and I can't work it out. So it's meant that every night I have to check the timing on the computer and make sure they're adjusted slightly manually to account for any errors that have occurred. That's a pain, but otherwise it's all worked out fine. It's risky, and chances are that one day there's going to be a major crash and the whole things going to grind to a halt."

For the live shows, Marks ideally likes to be able to choose the support acts and DJs to ensure that the whole evening ideal flows together and is more of an event than standard concert.

"One problem I've had in Europe especially is that I've ended up on gigs where there's been a couple of local DJs playing really hard techno, which isn't what I do," he explains. "I had this problem of having to somehow follow or lead up to that. People seem to accept it, but they're not as used to the idea of the live stuff and see it as a bit of a novelty. It is a bit annoying sometimes, so the idea is to try and have it under our control."
