Horse Thief are supposedly a 'psychedelic folk' outfit hailing from Oklahoma City, Oklahoma. You would, however, be forgiven for failing, completely, to identify the supposed 'psychadelic' elements on their debut EP, Grow Deep, Grow Wild, which in reality is fairly typical American indie rock.

After much digging, it appears the description 'psychedelic' has probably only been given as a result of the record's lyrics, which at times border on non-sensical – honestly, there's nothing else psychedelic about it; no tie die, no magic mushrooms, nothing. Case in point, 'I am the Bear' closes with the "Well I am the bear / and you are the tiger / and I will use my claws to protect her," which on reflection is less non-sensical and more of a mediocre metaphor.

Musically, 'Down By The River' is as psychedelic as it gets with a 17 second long intro constructed exclusively reversed sounds. After that 17 seconds though, its back to the guitar drive indie rock that constructs 80 per cent of the EP.

Cameron Neal's idiosyncratic lead vocals are perhaps the records biggest hurdle. Despite occasionally luscious music, the vocals will, to some ears at least, irritate. Which is a shame, because at times they end up more of distraction than the hook they should be. If you can get past that though, and perhaps even grow to like it, there's some decent music to be discovered.

Inaccurate descriptions and difficult vocals aside, the record is generally passable. Opener 'Colors' is a vibrant affair with all of the jolly glockenspiel you could ever want, which misleadingly positions Horse Thief as a sort of folk rock Sigur Rós with a splash of Polyphonic Spree (if you wanted to be really nice). After that though, it's all pretty much the guitars and drums until the EP draws to an end.

Closer 'The Magician' sees the equine pilferers approach their most folk-y. The track builds to a powerful crescendo, starting with plucked acoustic guitar and culminating with pacey, cyclical percussion, distorted leads and jangly melodies. It's the diamond in the rough for the album, a glimmer of potential in an otherwise middle-of-the-road record. If there's more from Horse Thief, it needs to be more of 'The Magician' and just so long as they don't fall completely into Mumford and Sons mould there's real potential.
