We are extremely psyched to debut the new single and video from Montreal producer/electro-pop heroine Caila Thompson-Hannant, aka Mozart's Sister. "Eternally Girl" is a huge, blindingly vibrant jam, teeming with dizzying, effervescent synthetic textures that should make her an honorary PC Music member. Thompson-Hannant's dazzling hyper-pop production is tempered just slightly and elevated to relatable anthem status by her soaring, heartfelt vocals, which lend the track its bittersweet but empowering human element. Check the Blake Gilley-directed video below, and look out for the limited Eternally Girl/Angel cassingle due next month on Arbutus, complete with a remix from PC Music/Kero Kero Bonito member Kane West on the b-side.
