This week we've been treating you guys to some interesting bits of video from Biffy Clyro, in which they talk us through their fantastic new double LP, Opposites. Today is no different and following videos about "The Thaw", "A Girl and His Cat", and "Accident Without Emergency" we today get a look at what the band have to say about the rather intriguing sounding "Spanish Radio". The track itself is one that'll grab your attention immediately when you hear the album, what with it featuring a mariachi band! They talk about the difficulties the guest musicians had with the timings and of drinking plenty of tequila after recording. Along with that you can stream the track in full below to see what they're talking about with a little more context. We'll have our final part of this series coming tomorrow, so keep your eyes pointed towards SKoA.
