Holy shit. Saw them yesterday opening for Tony Macalpine and this dudes are the real deal. I smiled throughout the whole gig just watching them play and how amazingly everyone is at their instruments.
Think of them as a Djenty/LTE/Plini/Periphery instrumental band. Fucking insane!
Don't miss the chance in catching them on tour. You won't regret it.
Edit: I have two Arch Echo CDs and their 1st vinyl for sale if you guys are interested. I bought their 3 releases at their show to support them (and got them signed) so now I have an extra copy of each release since I bought them before.
