I met him a few years ago in St. Pancras Station. I've seen him quite a few times heading to or from the Eurostar check-in with guitars and other luggage.
The newspaper has an interview with Jarvis by Olivia Laing and there are plenty of mentions of the importance of the quotidian and the everyday in influencing his music, and that of others.
He has a new book coming out later this month about his start in music and the influences of the everyday. It sounds similar to the work of Jonathan Meades.
I'm currently reading Jude Rogers' 'the sound of being human' which is also about the importance of music in shaping our lives and personalities and connecting us with the past. I'm looking forward to reading this.
