4tRECk was first played on NTS on 26 September 2017. Songs played include Pong Ping.

In existence for about 8 years, 4tRECk / Sam CALLOW makes music based around approaches, such as spontaeneous improvisation, chance, using instruments (piano, guitar, violin, accordion, home-made stringed instruments, percussion, voice..) the "wrong" way, inventive (perhaps illogical) ideas, and detailed composition … The results are entertaining, with a broad aural palette, and a melancholic undertow. The name 4tRECk is a contraction of 4track recording, referencing the humble beginnings of this "homme-orchestre".
