v.i.r.u.s.

Series of collaboration releases between Ryuichi Sakamoto and Alva Noto spanning from 2002 to 2011. The initial letters of the five installments - VRIOON (2002), INSEN (2005), REVEP (2006), UTP_ (2008), and SUMMVS (2011) - form the word "virus". In January 2023 a slipcase with its own catalogue number N-050 was made available by the label to house the LPs from the series (25870867). Since this slipcase was only sold empty, with the LPs available separately, it is not considered a valid box set item for cataloguing purposes.
