Confirmed by Myspace, which has them performing at Wesleyan University on the 6th of May this year, two weeks after they’re at Coachella.
So we’ve got a big rap act down. Based on previous years I would still expect another headlining act with indie cred, and a smaller opening act with indie cred… which doesn’t usefully narrow the field of existing artists.
Grainy two-year-old footage of the Clipse:
Although, anonymous respondent #21 on this ACB thread claimed earlier today that the full lineup will have King Khan and the Shrines joining Clipse and SONIC YOUTH (!!!), which would fit the established pattern and be fantastic. But Clipse is the only one of those confirmed so far, so as of now this excellent lineup is an only partially substantiated rumor.
Sonic Youth’s official site has the band booked through May, although there is a conspicuous gap between their shows in Luxembourg on April 26th and Brooklyn on May 16th. It’s possible that they could make it to Middletown halfway between those dates.
King Khan and company also have a May 6th gap on their itinerary – they’re in New York on the 3rd of that month, and in Boston on the 7th, so a stop at Wesleyan the day before the latter date is feasible.
But this is unsubstantiated! In the meantime, keep speculating. Post rumors/further substantiation as you wish.
