From that article: "‘Wicked Game’ is the song that everyone remembers but, if you listen to their earlier albums, ‘Silvertone’ and ‘Chris Isaak’ you can hear that Wilsey influence right from the start and the way they were developing their sparse, dreamy and atmospheric approach to the music. Listen to tracks like ‘Voodoo’ from the first album and ‘You Owe Me Some Kind of Love’ from ‘Chris Isaak’ and you can track a straight line to ‘Wicked Game’ as they build their sound and Wilsey refines his guitar tone, a tone he referred to as “Nitro Twang”. Wilsey himself said that he could reproduce his sound using any standard Stratocaster guitar and a Fender Silverfaced amp (he used a 1964 Fender Deluxe for the ‘Wicked Game’ recording) but it was never as simple as that."
