“For a ‘typical’ Fixx song, you might expect a solid, sync’d rhythm section, chiming guitars, animalistic keyboard sounds, and strong vocals,” he begins, “but I don’t think we dismiss an idea because it doesn’t sound like ‘a Fixx song.’ We might actually lean more towards one that isn’t an obvious Fixx song. There’s a couple on the new album that aren’t what we’d normally do, and because of that, rather than despite that, they made it to the album. On ‘Suspended in Make Believe,’ there’s aren’t any chiming guitars, and I ended up with a very strange sound. I have this Music Man guitar, an Axis Super Sport, with a piezo pickup so you can make it sound like an acoustic. I plugged that straight into a Fender amp and cranked it up. It’s got quite a strange, slightly grating sound. There’s also one called ‘Neverending,’ which almost has this arena-rock thing. It was starting to get a little bit Bruce Springsteen and, I mean, he’s great—but that’s not us. And then it started to get a bit U2-ish and we didn’t want that either, even though they’re great as well. And then Cy said, ‘Less U2, more New York Dolls,’ and I went, ‘Ah, that’s it. Now we got it!’ It’s not really like the New York Dolls, the way it ended up, but little comments like that can knock you sideways in a good way. Then you end up following it down another rabbit hole.”
