We got a preview of Julian Casablancas’s long-awaited sophomore solo alum last week when he shared a fuzzy, 2 minute teaser video for the upcoming record. Thanks to a quick-thinking fan, we now get even more material from yet-untitled release, as Casablancas debuted what seems to be a new song during a surprise show in Florida last night. With help from his new backing band The Voidz, The Strokes frontman performed “Ego,” and though the sound quality isn’t amazing it will definitely give you a good idea of what’s to come. Check it out above.
