On this week's episode, we welcome Erhan Alman, from the British metal band on everyone's lips Heriot on the cusp of the release of their full-length debut album, Devoured by the Mouth of Hell. If Carlsberg did metal album titles ... Erhan picked a show from one of the UK's premier math-rock acts, Oxfordshire based trio TTNG, from the 15th December 2011 at the historic Thekla venue in Bristol. TTNG (or as they were known then) had three years previous released Animals, an album that is often regarded as one of the best math-rock albums of all time. Their fluid clean guitar licks are some of the most melodious and technically impressive in the whole genre, which is perhaps why Erhan picked up the tablature (that's sheet music for all you non-guitar players) to that very album. Yes that's right, for one week, we are Calculating Infinite Tabs (© Simon Clark 2014) We delve into Erhan's love of all things math, discuss the rich history of Thekla (which, if you're unaware, is a motherfucking boat!) and try to wrap our heads around the absolute guitar wizardry of TTNG six-stringer Tim Collis.
