Haim and Christine and The Queens team up to cover Prince's "I Would Die 4 U"

The acts partnered during this past weekend's Boston Calling festival - Haim reeled off a lively rendition of Prince's classic, while Christine and The Queens (and her dancers) cut shapes behind.

This isn't the first time Christine and The Queens has paid tribute to The Purple One - she recently played the Prince-penned Chaka Khan hit "I Feel For You" on Later... with Jools Holland.

Haim are currently working on their eagerly awaited second record, and are roadtesting new material as they hit the summer festival circuit.
