Harras is an album of improvised music by Derek Bailey, John Zorn & William Parker.

Towards the end of the track "Evening Harras" there is 10 minutes of silence followed by a Bailey solo.

"[1] The Allmusic review by Dean McFarlane awarded the album 3 stars stating "Evidently the candid session that took place on a night in New York resulted in a chaotic collision of ideas.

With the performers being such strong voices individually, the abundant ideas fly in and out of the picture with no apparent regard to form; the session evolves from tepid beginnings into a no-holds-barred, rapid-fire assault on the senses.

Fans of ultra-high-energy free improvisation will find it a delight to hear these three masters sparring on this one-off collaboration, making Harras a vital historical document which requires the gumption of a hardened avant-garde music fan to take the whole recording in one listen".
