LONDON—A set of 107 non-fungible tokens (NFTs) representing images of cartoon apes sold for $24.4 million in an online sale at Sotheby’s auction house on Thursday, as the market for the niche crypto-asset continues to heat up.
The images were part of the “Bored Ape Yacht Club” collection of NFTs—a set of 10,000 computer-generated cartoon apes, made by the U.S.-based company Yuga Labs. Owners of the ape NFTs become members of an online club.
An NFT is a digital asset that uses blockchain technology to record who owns a digital object such as an image, video, or in-game item. While anyone can view the asset in question, only the buyer can say they are the “official” owner.
Unusually for NFTs, the buyers of Bored Apes also receive the intellectual property rights for the images. They are often used as profile pictures on social media.
The lot contained 101 of these anthropomorphic apes, with different combinations of features such as clothing, accessories, and facial expressions, plus the option to generate six new “mutant” ones.
The sale also included a lot of 101 “Bored Ape Kennel Club” NFTs—a set of dogs, marketed as pets for the apes. This fetched $1,835,000 and the set of apes fetched $24,393,000, bringing the total for the sale to $26,228,000.
Sotheby’s allowed payments in the cryptocurrencies bitcoin, ether and USDC, and fiat currency.
The frenzy for NFTs shows no signs of slowing. Sales volume on the largest NFT marketplace, OpenSea, hit $3.4 billion in August, up tenfold from July. Some speculators “flip” their NFTs for eye-watering profits within days or even hours.
The average weekly secondary market price for a Bored Ape has surged from around $1,500 when they were launched in April to $71,942 last week, according to NonFungible.com, a website that tracks the NFT market.
On Monday, a single Bored Ape sold for 740 ether (around $2.9 million).
Michael Bouhanna, contemporary art specialist at Sotheby’s, said that although there is financial speculation on NFTs, he sees the Bored Apes as works of art. He said the NFT market is not a bubble.
“People were talking about a bubble in March, in June, etc, and then we see that the market is even stronger today so I think they’ve been proven wrong … I think it’s a very organic market with great collectors who have great appreciation of art,” he said.
Luciano Berioʼs “Folk Songs”: Reconstruction of the Idea in the Context of Creativity

Relevance of the study. Luciano Berio’s vocal cycle «Folk Songs» for mezzo-soprano and seven instrumentalists (1964) was considered for the first time in Ukrainian musicology. The relevance of the research is determined by the imbalance between the high degree of performance demand of the work in the modern cultural space and the insignificant activity of its musicological study.
The purpose of the study. The purpose of the article is to reconstruct the creative idea of the vocal cycle «Folk Songs» by Luciano Berio in the context of the composer's searches, their mutual influences and interaction.
Methods. The article uses historical, cultural and biographical methods (to study the stages of the formation of the idea of the work in the context of the composer’s creative biography), source studies (to find the sources of multinational folk songs that became the basis of the vocal cycle), methods of comparison and analogy (to propose a hypothesis about the origins of the creative idea of «Folk Songs») and the method of theoretical generalization.
The results and conclusions. The biographical context and stages of creation of Luciano Berio’s «Folk Songs» are studied in detail, the sources of folk songs from five countries of the world (USA, France, Italy, Armenia, Azerbaijan) used by composer in the vocal cycle are determined. The main features of the formation of the unity of the cycle are considered: the general logic of the construction, the content of the texts, the composition of the instrumental ensemble, metro-rhythmic features. A hypothesis is proposed about the combined influence of the performing skills of Cathy Berberian and the linguistic and stylistic features of John Cage’s «Aria» (1958) on the formation of the idea of Luciano Berio’s «Folk Songs». The manifestation in the vocal cycle of Luciano Berio’s interest in the linguistic (phonological) aspect of creativity, which became active in his work from the 1950s, is emphasized. Based on the results of the research, it is proposed to perceive and realize «Folk Songs» as a link of two «lines» of Luciano Berio’s creative interests, manifested in his work — interest in multinational folklore and phonological features of different languages. Vocal cycles created in the 21st century based on the model of Luciano Berio’s «Folk Songs»: «Ayre» by Osvaldo Golijov, «Worksongs» by Samuel Blaser and «Chanzuns Popularas Romanchas» by Oscar Strasnoy were identified. These works indicate possible prospects for the continuation of the research topic.CBS 2 - Search Results
