English experimental band Portishead will tour North America in October, beginning with an appearance at All Tomorrow’s Parties. Fellow British band Thought Forms will provide support. Despite releasing just two albums in the last 15 years, demand is sure to be high. Grab limited-run tickets here through Thursday, 7/14. All other tickets go on sale 7/15 & 7/16, except in Chicago, where you’ll have to wait ’til 7/22.
