Australian electronic music band PNAU has released their new single, “Tu Corazón (Your Heart), featuring Mexico's The Warning. The song is a three-minute instrumental track that has been years in the making and is about opening your heart to the beauty around the world. The Warning were introduced to PNAUs when their project, Empire of the Sun, was filming in Mexico. The collaboration came to light when The Warning recorded the song in PNAUE's studio in downtown Los Angeles. The official music video was shot in Monterrey. This follows PNAUK's collaboration with Italian trio MEDUZA and a number of remixes with various artists.
