这张作品的由来已很难考据。包括这个组合也是无法考据组建时间，或者就是一个见光死的临时组合罢。依据里面有John Tchicai 的缘故，只能推断是John Tchicai 游历瑞士时与一众瑞典和丹麦即兴界的一次不期而遇。同时，这是一张现场录音作品，时间为1971年4月，组合来自美国、瑞士、丹麦三国共计12名乐手。
1971年John Tchicai 已是自由爵士的有数人物，相对于瑞士和丹麦的后进而言，John Tchicai 估计是要被奉为大神级的存在吧！但整场的演出并不是以John Tchicai ，更多的是集体的创作智慧。Anne Christiansen 的呓语，Irène Schweizer 与 Ole Thilo 之间键盘乐器的呼应，Jürg Grau 压抑的小号夹杂着阴郁的三个低声部，都在以叙事的方式演绎着北欧式即兴，冷艳而含蓄。不同于美国此时自由派的强悍，北欧的阴柔更契合其人文意识与美国的不同。
令人惋惜的是这个临时组合就出版这一张现场录音，更惋惜的是除了Irène Schweizer 与吉他手Stephan Wittwer 后续仍有不少作品问世，其余人员如风中飘零，并无多少作品出版，而这次北欧和美国的美丽相遇，剩下的就只有这唯一谜一样的现场录音。

In the '70-s, the peak years of Tomasz Stanko, his perfect partners were few, but certainly the Finnish drummer Edward Vesala and Polish tenor-man Tomasz Szukalski belonged to them. Their cooperation brought such important records as "Balladyna", "TWET", "Almost Green", "Live at Remont" or "Satu". These three musicians' mutual understanding was almost of a metaphysical quality, necessary to be sure, to play free-jazz. On this disc they are joined by the sensitive and articulate American bassist, Peter Warren. Cut in 1976, TWET (supposedly an acronym of musician's initials), is a perfect example of free-jazz attractiveness potential, so seldom truly realizes. But here it materializes, to the sensitive listener's satisfaction. Though Stanko's leadership is unquestioned, he leaves ample space for Szukalski, Vesala and Warren to stretch their music; not to mention whistle, cowbells and human voices.
"Dark Awakening" grips our imagination from the very start with the mysteriously oscillating mood, the sounds of bass clarinet... With the first sounds of trumpet the heterophony of the four instruments fighting for our attention unfolds.
In the title piece TWET ostinato basses support the convulsive flights of trumpet but soon bass itself comes to the fore with the series of three-notes motifs (c, c-sharp, d) crowned by a surprising consonance. The most gentle and even tender number, "Mintuu Maria" starts with tenor-trumpet dialogue that gradually gives way to tenor improvisation after which the trumpet joins again.
Strong drumming and bass figures introduce "Man of the North", giving way after a while to incoherent heterophony of voices leading to frenetic saxophone solo over assertive and faster bass walking. Out of the background to the fore the drums emerge, but the bass figures take over the high above the trumpet's soaring sounds appear. Another contrast brings "Night Peace": the chimes of steady basses, tiny bell-sounds and prolongated sounds of trumpet bring back sleepy saxophone, and they take rest of calm pulsations of drums and bass.
