Legendary free-jazz pianist Alexander von Schlippenbach joins the core trio Neukollner Modelle for this 2-CD follow-up to Sektion 1-2 (Umlaut, 2016). Here, top-flight European adventurists mold variable jazz vernaculars into a signature modus operandi, propelled by the superb Scandinavian drummer, Sven-Ake Johansson. Moreover, the program poses a mélange of rhythmically charged motifs, fractured voicings, and whirlwind-like improv segments amid the construction efforts and other parts where the band seemingly uses a wrecking ball to disassemble micro-themes.
von Schlippenbach's rapidly paced block chords and fragmented loops complement the quartet's dizzying ostinato grooves, alternating with lament and blustery outbursts. On "Sektion 4," Joel Grip's bowed bass lines help anchor the drummer's peppery snare drum hits, eventually leading to saxophonist Bertrand Denzler's forceful phrasings amid a few lighthearted episodes and veiled melody lines. The soloists also delve into some clustering sequences that often explode into asymmetrical free bop maneuvers and balls to the walls exercises on the power-packed and enduring "Sektion 6."
The final track "Sektion 7" clocks in at 33:59 and evolves like an improvisational suite since the band covers so much ground, starting with a tight-knit convergence, where von Schlippenbach dances around Denzler's plaintive cries and winding notes. The saxophonist incorporates circular breathing techniques as the musicians execute a variety of interesting mini-motifs throughout. Consequently, the music soars to lofty heights but is alto contoured with restraint as the artists reinvent themselves on a continual basis. Here, the quartet improvises at a higher-level, but equalizes the heady inferences with an entertaining gait. Essentially, they merge numerous abstract musical realms into a cohesive line of attack.
