During his creative life, Hardijs Lediņš kept much material about his activities: including poetry and other writings, music recordings, photographs, slides, and videos of performances. In the early 2000s, his friend and collaborator Juris Boiko came up with the idea to publish an anthology of the NSRD, or Workshop for the Restoration of Unfelt Feelings, a creative group they established in 1982, but the project was not realised before deaths of Boiko and Lediņš. In 2007, Hardijs’ mother Ruta Lediņa and his son Pēteris gave the Hardijs Lediņš collection to the Latvian Centre for Contemporary Art (LCCA). The anthology was produced by the LCCA and published in 2016 as part of the activities of Hardijs Lediņš Year in 2015, and manuscripts and visual material from the collection are widely used in it. Visual material from the collection is published on the website of the LCCA, and is part of the Europeana collection. The audio albums are published by the site ‘Pietura nebijušām sajūtām’ (Station of Unfelt Feelings, pietura.lv), which is devoted to the memory of Juris Boiko and Hardijs Lediņš. The site also publishes photographs, videos and publications by Boiko and Lediņš, and about them. The Hardijs Lediņš collection is a very well-documented history of one of the most significant phenomena in Latvian avant-garde art of the 1970s and 1980s. Its protagonists expanded the boundaries of the understanding of what art is, blending together poetry, music, video art, actions, performances, etc. Despite the unofficial character of NSRD activities, the record albums were quite popular with the younger generation, and were copied on to tapes. With the beginning of perestroika, the activities of the NSRD were legalised, they participated in some exhibitions, and in 1988-1989 they received international recognition with the exhibition ‘Riga-Lettische Avantgarde’ (Riga-Latvian Avant-Garde) in West Berlin, Kiel and Bremen. However, fame was also the beginning of a creative crisis and the break-up of the NSRD. Hardijs Lediņš and Juris Boiko started to work individually. Lediņš created the Approximate Art Agency, with the aims of organizing exhibitions and performances, producing publications, and working with new media. Boiko was a video artist and art curator. In the 1990s, public interest in their 1970s and 1980s postmodern avant-garde declined; however, it has revived in the 21st century, and Hardijs Lediņš Year in 2015 was a sign of this. There is also increasing interest abroad: for example, in 2017, records with two selections of their songs were published in Ghent in Belgium. In 2016-2017 artefacts of the NSRD were presented at the exhibition ‘Notes from the Underground. Art and Alternative Music in Eastern Europe 1968-1994’ in Lodz, Poland and Berlin, Germany. In 2017 – 2018, artefacts from the Hardijs Lediņš collection were exhibited in Žilina, Slovakia, and in Zurich, Switzerland in the exhibition ‘Poetry & Performance. The East European Perspective’.
