A$AP Rocky's "Sundress" was a breath of fresh air the moment it debuted in November, nearly 20 days after it had as an unsanctioned demo reel. Even hardened hip-hoppers were forced to lean back, at the thought of A$AP Rocky picking daffodils to the sound of a Brit Pop drum section. leaving no zero of Yam's sketch-up in passing.

But rest assured, A$AP Rocky's expanded musical horizons are a welcome addition in the greater sense of hip-hop. Part of the credit "Sundress" indubitably goes to his collaborators Tame Impala, whose influence is hard to mistake, if you're familiar with their solo material. For what it's worth, "Sundress" was one of two songs that Rocky previewed during last year's Camp Flog Gnaw with Tyler the Creator - the other being the unpublished "Shittin Me."

With Tame Impala booked to perform at week two of Coachella last night, the opportunity for Rocky to join them onstage was there for the taking and he did just that. They performed "Sundress" in unison, while also repackaging A$AP Rocky's "LDS" with the backing of the band's live instrumentation. Thanks to the vigilance of the Coachella crowd, numerous videos were recorded, documenting the whole affair in a series of amateur postings. See for yourself.
