Leaving five years between your debut album and its follow-up may seem like a high-risk strategy. For Dublin outfit Dirty Epics, however, the intervening time has clearly been well spent, including gigging around Europe and across the US, as well as providing songs for various TV and film shows. They’ve honed their sound, too, into a formidable, controlled sonic assault, while the songwriting carries the mark of a band who’ve got what it takes to scale the heights. There certainly isn’t much excess baggage on the 10 tunes on One Way Mirror, produced by Declan Gaffney, who has worked with U2 (No Line On The Horizon) and Matt Paul (Amy Winehouse and Hot Chip).
