It takes all of the first 80 seconds of Bristol trio Thought Forms second album, Ghost Mountain, to realise that this is a group who have moved on substantially from their debut which arrived 3 years previously. Indeed, if their self-titled debut in 2009 was about finding the dynamic limits of their atmospheric sound, gently prodding and probing varying elements, then the huge great slab of guitar that greets you instantly on their follow-up roars with the confidence of a band who've found their level from which to fully explore their creative expression.
