Trombonist Brett Sroka may be an Ellington freak but he is also a film composer and a member of psych noise collective 12,000 Trees. He is down with jazz cats: he's worked with Jason Moran, while the magnificent Mary Halvorson turns up as a guest. But If Not Inertia, Sroka's third release in his Ergo guise, is closer to the guitar and laptop haze of Vienna's Christian Fennesz, or perhaps a less global version of the Fourth World experiments of Brian Eno and Jon Hassell. It comes with the instruction “File under: jazz/electronic/experimental”, while Sroka himself is described as equally inspired by Sun Ra and Sigur Rós. In fact, we don't really get the Icelandic band's post-rock climaxes, but there are certainly hints of Herman Poole Blount – not as cosmic bandleader but in his sometimes neglected role as synth and electronics pioneer. If Not Inertia is a record of shimmers and swirls, of textures so vivid they are almost tactile.
