Unsquare is a 2008 studio album by Maybe Monday, a San Francisco based experimental electroacoustic improvisation music ensemble featuring guitarist Fred Frith, koto player Miya Masaoka and saxophonist Larry Ochs.

It is their third album and includes guest musicians Gerry Hemingway, Carla Kihlstedt, Ikue Mori and Zeena Parkins.

In a review of Unsquare at All About Jazz, Kurt Gottschalk called Maybe Monday "a ridiculously strong trio", and described their collaboration with Hemingway, Kihlstedt, Mori and Parkins on this album as "a dizzying, fascinating set of music".

[4] Reviewing Unsquare in DownBeat, Bill Shoemaker was initially concerned that the presence of guests on Maybe Monday's third album would upset the "alluringly precarious elegance and intensity" of their earlier work.

[1] Shoemaker felt that the way the instruments connect, "the twacks of koto and low-register harp; the gravelly drones of guitar and laptop; the smudges of reeds and bowed strings", explains the growing interest in electro-acoustic improvisation.
