[1][2][3] In a review for AllMusic, Eugene Chadbourne wrote: "Swiss pianist Irène Schweizer's solo concert of May 25, 1990, was close to breathtaking; she deserves every last clap of applause that we hear... it is in the most abstract pieces, 'Serious Hanging Out' and the inside-the-piano 'Chuschtenploz,' that she comes up with the set's finest music.

"[4] The authors of the Penguin Guide to Jazz Recordings awarded the album 3½ stars, and stated: "Brief and apparently inconsequential structures are delivered without elaboration and there is a meditative stillness to much of the music... 'Sisterhood of Spit' is a name that refers to an all-female collective of the '70s.

It's dedicated to the late Chris McGregor... and also to saxophonist Dudu Pukwana.

It both reflects and ironizes the spirit they evoked... [The record is] faithfully and accurately registered, picking up Schweizer's softest figures and sustains, and handling the loudest and most impactful moments without distortion.

"[5] Author Todd S. Jenkins noted that the album provides "an unobstructed view of Schweizer's essential techniques," and commented: "a different aspect of the artist's personal vocabulary is demonstrated on each track, a virtual roadmap of her musical mind.
