At Global Towers we developers have 10% time to go away and hack at something that might, ultimately, bring value to the business. So that means Friday afternoons is hack time. One of my personal hack projects has come to an end and I wanted to record it for posterity before it disappears - how it behaves, what it does, the thought process behind it and why I thought it was a valuable exercise.

Steve Harris loves The Gaslight Anthem. 'The '59 Sound' was his album of 2008, and the latest one, 'American Slang' is equally popular in the Harris penthouse.

So imagine Steve's delight when GA frontman Brian Fallon came into Xfm Towers to chat about the band's current tour and play three songs on acoustic guitar.
