The first disc was recorded at WKCR in June 1978 and features Mark Abbott, Polly Bradfield, Eugene Chadbourne, and LaDonna Smith and Zorn on 6 different takes of "Lacrosse".

The second disc is the original recording of "Lacrosse" which was made by Eugene Chadbourne, Henry Kaiser, Bruce Ackley, and Zorn (dubbed "Twins") in San Francisco, California in June 1977.

The Allmusic review by Joslyn Layne awarded the album 4 stars stating "This box set is for dedicated fans already intrigued by the early annals of Zorn and his musical game theories.

[2] The Penguin Guide to Jazz said "Historically this is arguably as important a set as any Blue Note or Prestige milestone... one can often hear things in this collection which echo more vividly than much of Zorn's more obvious 'outrageous' work".

Formed by Zorn's formal instructions or moves chosen by the player, the recordings collected here present a discontinuous world of discrete sounds.
