This double LP with 16-page booklet is the extensive documentation of the exhibition "Godspeed in 4/4 Time" at the church St. Matthäus in Berlin, where artist William Engelen installed an instrument consisting of 366 metal tubes that was on display from May to September 2025. The tubes were mounted next to each other surrounding the nave of the church. Each tube was unique and differed from the others in length, diameter, thickness and/or material (copper, brass, stainless steel, aluminium), and gave a different sound. The design of the instrument may be read as a graphic score that represented one calendar year.

One possible way to play the score was to walk through the room and strike each tube. Visitors were allowed play the instrument themselves and realise the score in different ways. On a number of days, musicians were invited for concerts on the tubes combined with their own instruments. Among others, these concerts featured: percussionists Evi Filippou, Robyn Schulkowsky and Marius Wankel playing the metal tubes; Zinc & Copper (Robin Hayward, Hilary Jeffery and Elena Kakaliagou) playing brass instruments together with Robyn Schulkowsky on the tubes; Spill with Magda Mayas on piano, harpsichord and chest organ, and Tony Buck on the metal tubes.

The double LP includes recordings of all these groups on sides A to C, followed by a solo improvisation on a single tube by William Engelen on side D. The performances were recorded and mixed by Adam Asnan and mastered by Giuseppe Ielasi. The LPs are housed in a gatefold sleeve and accompanied by a full-colour 16-page booklet documenting the installation and concerts in beautiful photos, texts, and more.
