*150 copies limited edition*  The Belgian free jazz scene of the early 1970s remains criminally under-documented. While Fred Van Hove's participation in the legendary Machine Gun sessions (1968) with Peter Brötzmann, Han Bennink, and Evan Parker placed Antwerp on the international map, a wild ecosystem of temporary combos and performative madness flourished in the shadows. The WIM (Werkgroep Improviserende Musici) collective - founded in 1972 after Van Hove and saxophonist Cel Overberghe refused to play Jazz Middelheim in protest of pay disparities between European and American musicians - became the crucible for this activity. Van Hove, André Goudbeek, and Ivo Vander Borght were its main protagonists, but dozens of musicians passed through its ever-shifting formations.

The Tweeters emerged from these ashes. A sextet whose members had all circulated through the WIM orbit: Ronnie Dusoir had played with Van Hove and in The Kris Wanders Quartet; Paul Feyaerts and Dusoir were both part of The Full Moon Trio with Goudbeek; Liliane Vertessen - later to become one of Belgium's most celebrated visual artists, her work collected by M HKA and the Flemish Parliament - and her partner Jean Van den Plas had improvised with Julian Beck's Living Theatre. Saxophonist Edmond Van Lierde had played alongside his then-partner Nicole Van Den Plas (who would later relocate to Germany and collaborate with Sven-Åke Johansson, Alfred Harth, and Thomas Cremer) in countless ad-hoc groupings.

The band's name? A wordplay on the Dutch word for twins - tweeling - most members sharing the Gemini star sign. Their first concert probably took place at King Kong in Antwerp. No one remembers exactly.

These tapes from May 1976 capture the group in Berchem - free jazz and prog colliding in four extended pieces. Ultra Eczema launches its Pedantwerp archival series with this first-ever vinyl release: recordings made in Antwerp between May 1968 and the end of times. Hold on to your hats.
