Underworld’s second album, Second Toughest In The Infants, has just been re-released as a super deluxe four-disc box set, and I’m pretty sure it would gain a place on my Music to write by playlist. The original version was released in 1996; compared with its predecessor dubnobasswithmyheadman, it took me a while to get this album. Now, it makes me think of brutalist architecture: abstract, uncompromising and starkly beautiful. And it’s ideal listening when you need to concentrate fully and write fast. The vocals are sparse and fragmented enough not to hijack your train of thought, and the first track ‘Juanita / Kiteless’ is filled with a building, nervous energy. The skittering, snapping snare and tight beats kick in straight away, grab you by the collar and say: enough procrastinating. Get on with it now.

So – what are you waiting for?
