Sparkler is a dreamy shoegaze/dream pop band hailing from Philadelphia, Pennsylvania. Primarily the project of Chris Schackerman (vocals, guitar, bass, synth) often alongside Sarah Chrest (vocals, guitar, bass), they craft lush, reverb-drenched soundscapes characterized by ethereal vocals and shimmering guitar textures. Since forming around 2017, Sparkler has built a dedicated following within the indie scene through a steady stream of self-released and label-backed material (including releases on Crafted Sounds, Z Tapes, and Drunken Sailor Records), capturing that classic shoegaze vibe with a distinctly modern, melancholic warmth.
