“We started writing ‘Toluca Stars’ in Mexico, in a hotel on the outskirts of the City of Toluca”, says Underworld's Karl Hyde.
Due for release on 25 October, 'Drift Songs' marks the conclusion of their hugely ambitious, 52 week 'Drift' Series.
The new track is the first installment in the third part of the electronic music pioneers' on-going, cross-platform project.
'Drift' has attracted considerable critical acclaim, with Mojo declaring it "a torrent of ideas, with its own internal logic."
