On November 7, 2025, the Belgian label Sdban Records will release a reissue of the mythical Open Sky Unit (1974) by the eponymous jazz fusion group featuring Micheline and Jacques Pelzer, Steve Houben, Ron Wilson, Janot Buchem and Michel Graillier. The album returns on vinyl, highlighting a pivotal moment in Belgian jazz history, where soul, funk, and free improvisation came together in a vibrant and family-driven project.

Formed in the early 1970s as a homage to Dave Liebman's group Open Sky, Open Sky Unit grew out of informal jam sessions in Liège, Belgium, into a unique collective. One of the central figures was Jacques Pelzer, father of drummer and vocalist Micheline Pelzer, alongside his second cousin, saxophonist/flutist Steve Houben, bass player Janot Buchem, percussionist Michel Graillier and American pianist/composer Ron Wilson.

Their 1974 debut album was released on the Duchesne classical music label, run by Pelzer's brother-in-law. The group's sound carefully balanced jazz and soul and was largely directed by Wilson, a Californian pianist and singer who settled in Liège and nearby Maastricht after his army service. Wilson composed the entire repertoire. Open Sky Unit was recorded live at Jazzland club in Liège, and the band made several short tours in Belgium and abroad (including Tunisia) until around 1975-1976, when Houben left for Boston to study at the Berklee College of Music.

Although the original live recording from 1974 was not technically perfect, the group succeeded in capturing their heartfelt live energy. Tracks such as Open Sky, Sunshine Star, and Passion and Compassion are striking examples of this. Years later, the album version of Sunshine Star found its way onto Funky Chicken (2014), the compilation that not only brought the track back into the spotlight but also marked the beginning of Sdban Records.

In addition to the standard reissue, a limited edition of 200 copies will be released for collectors, featuring a 7" single of Ron Wilson's Sunshine Star as a special bonus. This single was originally released in 1973 with the acoustic version of Sunshine Star (piano and vocals) on the B-side, recorded a few months before the longer jazz-funk version later featured on the LP Open Sky Unit. The A-side, Peace Is The Answer, was only released on that single at the time and is now being reissued for the very first time. The 7" is thus a faithful and long-awaited reissue of a rare piece of Belgian jazz history, it's intimate, soulful, and an ideal complement to theexisting and well-known LP.

Although the band never achieved a major international breakthrough, they were highly valued in progressive European jazz circles and later secured a place in anthologies such as Utopic Cities: Progressive Jazz in Belgium 1968-1979. The reissue of Open Sky Unit brings their music back into the spotlight and reaffirms their role as key figures in the Belgian jazz scene of the seventies.
