Hidden in the Stomach is the debut album by the AALY Trio + Ken Vandermark, which was recorded in 1996 and released on the Swedish Silkheart label.

AALY Trio is a Swedish free jazz band composed of saxophonist Mats Gustafsson, bassist Peter Janson and drummer Kjell Nordeson.

Nordeson is Gustafsson's oldest playing partner, their work together dating back to shared childhood in the northern city of Umeå, while Janson joined the group rather recently.The band has also existed in a quartet version with pianist Per Henrik Wallin.

The FJF debut, Blow Horn, includes a different version of "Structure à la Malle", with the same basic formal skeleton but without the composed melodic theme heard on Hidden in the Stomach.

[1] In his review for AllMusic, Brian Olewnick states " The playing is often turbulent and roiling, but never wanders so far afield as to become divorced from the structure of the compositions, which tends to be blues based or even noir-ish.
