A blimp decorated in the Aphex Twin logo was spotted hovering above the Oval Space in Hackney on Saturday (August 16).

The airship also featured the digits “2014”. Now, in a further development, the same logo has been spotted by fans outside Radio City Hall in New York.

In June, fans of Aphex Twin (real name Richard James) purchased digital copies of his rare album Caustic Window via a Kickstarter campaign. A physical copy of the record – which only reached the pressing phase in 1994 before being scrapped – was auctioned on eBay and sold for £27,198. Money raised from the sale was reportedly split evenly between those who paid into Kickstarter, James himself and an unnamed charity.

In 2010, James announced that he had completed six albums, as well as “loads of tracks which don’t belong anywhere”.

“Two are very non-commercial, abstract, modular-synthesis, field recordings – those I finished four years ago. Another one is ‘Melodies From Mars’, which I redid about three years ago,” said James.

He added: “There’s one of stuff I won’t go into; a comp of old tracks. Which is never really finished and always changing; and then one I’m working on now. There are also loads of tracks which don’t belong anywhere.”

Despite this, a new record has not been forthcoming, with his most recent studio album, Drukqs, released in 2001.
