Did you ever wonder who made Japan’s earliest musique concrète and how it sounded? Ubuweb, a one-stop hub for everything obscure that was founded by poet Kenneth Goldsmith in the ’90s, collects such things. Russell Haswell alerted us to the site’s trove of early Japanese tape recordings that were recorded at concerts in Kioi Hall between 1953 and 1956. We’re especially into Toru Takemitsu’s “Clap Vocalism,” which seems to provide a perfect sample bank for your next remix. Check out the full collection here.
