Tomorrow, Philly-born electronic pop outfit Sun Airway releases its second album, Soft Fall, on Indiana-based indie label Dead Oceans. The album is a sonic leap forward for the band, carrying a pulse and urgency that its 2010 debut Nocturne of Exploded Crystal Chandelier only hinted at. But this isn’t a reinvented Sun Airway, but a refined one – band leader Jon Barthmus and his crew of collaborators continue to explore dreamy, blissed-out atmospheres and sonic territories, but this time its been shaped by two years of ideas and experiences. I’m excited to dig into the album this week on Unlocked, The Key’s regular spotlight on new and significant releases from Philadelphia artists. Tomorrow, I’ll review Soft Fall; later in the week, we’ll discuss the album with Barthmus, and explore its video and design components. Today, to set the scene, we’re spotlighting the song “Close.” This was the first single we heard over the summer, and it still feels like the song rushes right out in front of you at a vigorous, exciting pace. Thanks to the band, we’re making it a free download for the next 24 hours, so grab your mp3 below, and check back later in the week for more on Soft Fall. UPDATE: 24 hours are up! Listen to the song in the YouTube player you see below, and stream Soft Fall in its entirety at MTV Hive.
