This has to be some kind of record. It's October 21 and we already know at least one act confirmed to appear at Ultra Music Festival 2011. Today, Crystal Castles' publicist sent out a press release confirming a North American spring tour which includes a March 26 stop at Ultra.
The duo performed here in September to a sell-out crowd at Grand Central, so expect their appearance at the festival to be a highlight.
Still no word, though, on Ultra's ticket prices, venue, or the number of days.
UPDATE: Ultra Music Festival will be taking place March 25 to 27, outside of the WMC dates.
