The return of south Wales' utterly wild, cosmic, nature-attuned four-piece ISLET is enormously welcome news.

Their new album "Released By The Movement" is an ambitiously explorative work, an intense and immersive follow up to their celebrated debut "Illuminated People".

Opener "Triangulation Station" is freaked-out psychedelic circus soundtrack , with vocals thrown back and forth between Mark and Emma, bowled along by tricksy drum parts and twisted tangles melody.

It's an opening burst of brightness that bears witness to the unbridled joy of their explosive live shows.

They sing without words at all, as the record plunges into the more nocturnal sounding "Tripping Through The Blue Room".

Woven together by John Thomas's guitar and Alex Williams's bass, this track is seized by the almost gothic dread that snakes through the record.

These songs were recorded with the band's good friend Stephen Black - also known as the artist SWEET BABOO.

With Black on the controls, the album was recorded and mixed in practice spaces and bedrooms in Cardiff with no engineers or outside input, giving the group the freedom to work without inhibition, recording stream-of-consciousness sonic journeys alongside unruly maximalist adventures.

ISLET reinvent themselves with every song, playing each others instruments, drumming over drums and splashing sonic colours over each others parts.

This recording draws heavily on the intensity and energy of ISLET playing together as a band.

Their often unpredictable live shows incorporate elements of hallucinatory ceremony and perfor-mance art and this is evident in this album.

Their naturally experimental approach and their own unique inner logic has created these nine unworldly jams, a window into their own unorthodox world.

This is a genuinely left-field record, a record that rings with defiance.
