Hexensabbat (Witches' Sabbath) is a solo piano album by Irène Schweizer.

[2][4] In a review for AllMusic, Eugene Chadbourne wrote that the album "takes a well-used, and quite practical approach of combining live and studio performances.

From the former event comes 'Rapunzel...Rapunzel', one of the performances from this pianist that approaches masterpiece status... [She] has a rowdy sense of humour... not only present in titles such as 'Dykes on Bykes' but in some of the chances she takes as an improviser.

"[5] Ken Waxman of JazzWord stated that "Folks looking for the roots of Schweizer's mature style as well as some fine music will easily find it on this set," and noted that Schweizer "rotates her presentation between sections of flowering European classicism to periods when it sounds as if she's panning for gold inside the instrument.

At times it appears as if we're hearing a duet between keyboard expression on one side and crashing cymbals and balls percussively flung onto the copper and steel strings on the other.
