The first thing you notice about Cardiff band Islet's second LP, Released By The Movement, is that it sounds familiar. There are many points of reference for this band but it's hard to put your finger on exactly what they are trying to achieve. It's not a dull kind of familiar by any means, there's something heartening about this album because it shows a build on the apparent aptitude of their debut Illuminated People, which seems to stem from the fact that Released By The Movement feels like the next bold and explorative push from this band.

It's a step in the right direction, although it's a bit tricky to really decipher what direction that is; this is a pretty eclectic and all over the place record. Recorded in a variety of locations across Cardiff - which is apparent in the changeability - this is an album that to a certain an extent verifies this band's cult following and guarantees that more will join, intrigued by the unpredictability. Even after a lot of listens, it's a big ask to seek an explanation as to why this appeals, but it does have charm, a kooky charismatic flavour with a decent aftertaste.

The album showcases this band's varied interests and influences, spanning genres such as psych, krautrock, tropical, psychedelia, post-rock and shoegaze - explored on what is an idiosyncratic proposition that provokes more than a few positive eyebrow raises. There's bits of the Yeah Yeah Yeahs, Portishead and The Cure all lurking in there too, making up a schizophrenic medley that could be headache inducing, but is actually pretty pleasant and enjoyable.

Opening with some trippy vocals from Mark and Emma on 'Triangulation Station' - a five minute long track that's, quite frankly, as bonkers as a Frank Zappa sing-along on acid - it manages to be both very groovy and as sinister as children singing. After opener 'Triangulation Station' you do hope that they will keep up the bonkers level, maybe even revving it up a but, but sadly they play it a little safe. What we have here are nine articulate tracks that vary in length but are equally brave and justified, offering space-jazz freak outs, convulsing synths and guitar progressions aplenty.

Produced by their buddy Stephen Black (aka Sweet Baboo), tracks range from the whirling drone fest 'Tripping Through The Blue Room (Part II) - named in homage to a song by intriguing 60s musician Michael Yonkers - to the seven minute atmospheric trounce that is 'Citrus Peel'. 'Tripping Through The Blue Room' is a good old indulgent two-part instrumental affair that pushes plenty of boundaries. The vocals do drown a bit on 'Carlos', but overall they remain sturdy and oddly languorous - with Emma proving to have both an unnerving and accessible style of singing.

There are highs and lows on this trippiest of trips: 'Mirror Me' is only attention-grabbing (and it's a soft clench at that) thanks to the organ sound making it feel like it could have been recorded in a castle, bringing in a gothic medieval element, and the strong production on 'Rip Bark' saves it from being a little too jingly-jangly, though it's still not particularly memorable and a bit of an ugly duckling on what is a graceful swan of a record.

Released By The Movement is bemusing to say the least. Here we see Islet move away from the dominant sound on their last LP and, even though the bravery is interesting and should be applauded, it does get confusing at times. Islet are a strong live band and have fortunately just about managed to capture some of the precision and power that goes into their performances after Illuminated People failed to live up to this particular challenge. A live album would be an intriguing offering though.

This sparkly and immersive treat of a record indicates that this Welsh band are still trying a little too hard, but that's absolutely ok if the results are as stimulating and explorative as this album. It appears that Islet have started to find their voice, which is still a bit too quiet but has the potential to be turned up.
