Emily Sprague is a composer, songwriter, producer, and multi-instrumentalist best known as the frontwoman and creative force behind Florist. Alongside the band’s intimate, often deeply personal songwriting, Sprague has developed an extensive body of solo work centered around modular synthesis, acoustic instruments, and experimental composition. Her albums Water Memory, Mount Vision, and Hill, Flower, Fog explore the space between ambient music and more traditional songwriting, often growing out of improvisation and close attention to texture and sound.

Sprague has also brought that experimental approach into her work as a producer and engineer, developing a highly personal relationship with recording technology and the studio itself. Her new album Cyano, coming this fall on RVNG Intl., continues that evolution while placing her voice more prominently within her electronic and ambient work.

Today’s 4ms Podcast guest is Grammy Award-winning producer and engineer Sylvia Massy, whose credits include Tool, System of a Down, Red Hot Chili Peppers, Johnny Cash, and many others. Her work has contributed to numerous diamond- and platinum-certified records throughout her career. We discuss recording techniques, unconventional approaches to sound, and the creative process behind some of her most influential work.

Kaitlyn Aurelia Smith found her voice when a neighbor lent her a Buchla 100 synthesizer in 2011. Buchla, and other vintage rare synthesizers became the heart of a body of work that includes Euclid, Ears (named one of the best albums of 2016 by Pitchfork, NPR Music, and Resident Advisor), The Kid, The Mosaic of Transformation, Let's Turn It Into Sound, and last year's Gush and Thoughts on the Future as well as her upcoming album RUIN: It’s Not Just Music - which comes out Oct 2nd.

She's made records with synth pioneer Suzanne Ciani (Sunergy), composer Emile Mosseri (I Could Be Your Dog / I Could Be Your Moon), and Hot Chip's Joe Goddard (Neptunes). She's remixed Max Richter, Perfume Genius, Danny Elfman, and King Gizzard & the Lizard Wizard, been remixed by Four Tet, and scored the film Omni Loop, starring Mary-Louise Parker and Ayo Edebiri.

This year she launched her own label, Someone Special, and its first release is her new album, Ruin: It's Not Just Music, out Oct 2nd - which is a Drum and Bass inspired album.

In this episode we get deeper with Kaitlyn's background, philosophy, and creative process.
