A pause, an industrial murmur, a warning siren and then Strangeness Oscillations kicks in with a crashing fractured beat, sporadic electric bass, howling penetrative sax and crunched guitar. The sax roils over it all and the melée grinds on before scratching to a halt. That's track one – ‘First Idea part 1’. Then a quiet simmer of bass and drums, plus quivering electronics, buoys up a leisurely low-register bass clarinet through a minimal bluesy shuffle and a slightly dub-style guitar solo. That's track two – ‘Bass Clarinet One’. Then a raucous sax and dirty bass guitar … are you getting the picture?

There's a willful inconsistency about this album, defying you to have expectations yet impressing you with whatever comes next. In quantum science 137 is the number that just might hold everything together and Strangeness Oscillations are a feature of the most fundamental particles. Perhaps it's a statement about the four members of the band getting down to basics, stripping away unnecessary elaborations and constructions. Just look who they are: Portishead guitarist Utley, Get The Blessing's Barr, Polar Bear über-drummer Rochford and the near-legendary Stabbins, suddenly returned from a 10-year musical hiatus away at sea. This project emerged from two days of intense improvisations boiled down to a 44-minute roller coaster that radiates the glee they must have felt just being themselves together.

It's a brash swagger of a thing from four musicians who know their own accomplishments and can revel in them.
