Grammy-nominated producer, engineer, mixer and songwriter Bill Reynolds has built a formidable studio career while also playing bass for several artists. Originally from Asheville, North Carolina, Reynolds left a full-ride scholarship to Appalachian State for classical bass performance to tour with the Sub Pop records band The Blue Rags. After two full-length albums and 5 years of touring, he built a recording studio in Asheville where he made records for the next 7 years while actively touring with various bands including Drugmoney and Donna the Buffalo.

In 2007, while co-producing and engineering the Avett Brothers' Emotionalism at Echo Mountain Studio, Reynolds met Band of Horses who were coming in to work on their album Cease to Begin. They quickly became friends and front man Ben Bridwell asked Reynolds to join the band when they began touring in support of the record. In 2010, their album Infinite Arms was nominated for the Grammy award for Best Alternative Album. Reynolds contributed production, engineering, bass, and a co-write for the song "Life on Earth," which was included on the Twilight: Breaking Dawn Soundtrack. Many more of his songs have found homes on hit TV shows, including House, Justified, Army Wives, and You.

Reynolds has mixed albums for Truth and Salvage Co., Floating Action, Sea Stars, and Band of Horses' live album "Acoustic At The Ryman". Reynolds also co-wrote and produced the song "One, Two" with Lissie for Harrison Ford's film Paranoia, and three songs on her album "Back To Forever". In late 2013, Reynolds relocated to Nashville into Jay Joyce's former studio. He has since produced, engineered or mixed Carl Broemel (of My Morning Jacket), The Watson Twins, Lissie, Milo Greene, Midland, Emily West, Deadfellow, Birdcloud, David Wax Museum, Bryan Ferry, Tyler Ramsey, and Braison Cyrus. Bill also toured with Michelle Branch playing bass.

In 2019, Reynolds composed the musical score alongside his friend Stephanie Nicora for "Public Trust", a documentary about public lands released by Patagonia. When he wasn't working on the documentary, he was busy writing with other artists and composing music for commercials into early 2020. In July of that year, Reynolds started working for Apple Music Country as a producer of various artist-led radio shows.

In 2025, Reynolds launched his project Feel Spektor, releasing the "Old Hickory Power" EP on Tuff Glove Records. The five-song collection serves as a musical portrait of Old Hickory, Tennessee—the town he calls home. Reynolds creates a sonic landscape that mirrors Old Hickory itself: rooted in tradition while embracing what comes next. The EP explores the tension between Nashville's rapid transformation into a cosmopolitan destination city and Old Hickory's determination to maintain its distinct identity and authentic community spirit.
