The 10th anniversary festivities for the Peter Brötzmann Chicago Tentet continue this week with performances by a number of killer spin-off projects. On Wednesday at the Hideout the superb reeds trio called Sonore (pictured) reconvenes. Brötzmann, Ken Vandermark, and Mats Gustafsson formed this configuration about four years ago and recorded an excellent album called No One Ever Works Alone (Okka Disk, 2004) that challenged the status quo of the all-saxophone group, keeping things fully improvised but generating pieces marked by the kind of compositional logic that arises when musicians share sensibilities and thoroughly understand one another’s art. Both on the record and at a stunning live gig back in 2004 at the Empty Bottle, the trio ran a sort of musical relay race, using spontaneous riffs as launch pads that the other players either embraced or rejected. But rather than the hot-potato back-and-forth, these guys focus on sustained development and intense interaction.
