X-Legged Sally (XLS) is a Belgian avant-garde rock/jazz-band founded in 1988 by composer Peter Vermeersch, and disbanded in 1997. They were one of the first bands from Belgium to combine a set of very different musical styles (jazz, rock, improvisation and classical), becoming a starting point for the Belgian indie music scene that developed in the nineties. Biography Initially, X-Legged Sally was formed to compose and perform the music Peter Vermeersch wrote for dance productions, such as Immes das Selbe Gelogen (Always the Same Lies), released as a live cd in 1991. Vermeersch' composing style was becoming too demanding for the constraints of sheet music such as was used in his earlier band Maximalist!. From the beginning, improvisation played an important role in XLS' songs. The first X-Legged Sally concert took place in november 1988. Soon, XLS became a band in its own right, although there would be cooperations with dance ensembles t
