"IBM 1401, A User's Manual" is a captivating exploration into the world of neoclassical music, crafted by the innovative Icelandic composer Jóhann Jóhannsson. Released on October 30, 2006, under the esteemed label 4AD, this album is a testament to Jóhannsson's unique ability to blend the cold, mechanical sounds of vintage IBM hardware with the warmth of classical instrumentation. The five-part composition, spanning 42 minutes, is a journey through the eerie beauty of obsolete technology, each track named after a specific IBM component, culminating in the hauntingly titled "The Sun's Gone Dim And The Sky's Turned Black." Jóhannsson's masterful use of piano, strings, and found sounds creates an atmospheric soundscape that is both evocative and introspective. This album is a striking example of Jóhannsson's signature style, where the past and present collide to create something entirely new and unforgettable.
