We've always tried to do different things with the sound of the band, but with this record we've tried to keep the essence of what it is to be a rock 'n' roll band at the forefront. I suppose that is a radical sound because there's not that much of it out there.

Starting a band is the easy part. Once you've formed the band, you have to tell a story, and that story requires songs. And not just good songs, but great songs. After a while, great songs won't do - they have to be the best. Success doesn't make it any easier. Each time I start a new record, it's a brand-new search.

A trumpet sounds pretty much like a trumpet, and that's true of a lot instruments; pianos sound like pianos, but there's something about the guitar - the range of possibilities is much broader.

Jazz came out of New Orleans, and that was the forerunner of everything. You mix jazz with European rhythms, and that's rock n' roll, really. You can make the argument that it all started on the streets of New Orleans with the jazz funerals.

We want this record to be something that people really listen to, rather than just have in their record collection.

One of the good things about globalization is it has created a single international music community, and I feel very much part of it.
