The 45-year-old electronic musician and composer performed in the U.S. for the first time in eight years on Saturday (17Dec16).
Playing a set at Houston's Day for Night festival alongside Bjork and Run The Jewels, he treated fans to a handful of tracks, including Polynomial-C from 1992's Xylem Tube EP.
In addition to his performance, Aphex Twin, real name Richard D. James, also put a new record up for sale.
The all-white 12" record was put for grabs at the merchandise desk and includes no text except for logos for Warp records and Aphex Twin, as well as the festival's date and location, "Houston, TX 12.17.16."
A festival representative has confirmed the authenticity of the record to Pitchfork.com; however, no further details have yet been released.
Earlier this year (16), Aphex Twin released a seven track EP called Cheetah. He's also booked for a string of dates across Europe next year (17), including Barcelona's Primavera Sound and Field Day London Festival.
