Live in Middelheim 1999 is a live album by John Zorn's Masada recorded in Antwerp, Belgium.

[1][2] The Allmusic review by Steve Loewy awarded the album 4½ stars stating "Every album by John Zorn's Masada seems better than the last, and this one is no exception.

By the time of this recording the group was a tightly cohesive unit, performing at an extremely high and satisfying level... With a recording time nearing 80 minutes, and substantial contributions from the entire quartet, the recording marks not so much a milestone in the life of the group as a symbol of its ability to constantly expand upon itself and draw on its not inconsequential roots".
