Described as “one of the greatest improvising violinists in America today” by virtuoso mandolinist/composer Mike Marshall, Alex Hargreaves is a fiddler who draws inspiration from a wide variety of genres and traditions. Based in Brooklyn, NY, Alex has toured with Jerry Douglas, David Grisman, Bela Fleck, Danilo Perez, Sarah Jarosz and has performed with many others including Punch Brothers, Sierra Hull, Steve Martin and Kacey Musgraves, appearing on her Saturday Night Live debut. He was a member of the Grammy award-winning Turtle Island Quartet from 2016–2019, appearing on their 2018 release, Bird’s Eye View, and can often be heard playing in the house band on the public radio variety show, Live From Here with Chris Thile.
At age 17, Alex, along with bassist Paul Kowert (Punch Brothers), teamed with Mike Marshall to form The Big Trio, performing together extensively following the release of their self-titled album in 2009. From 2007–2014, he toured with Grammy-nominated singer/multi-instrumentalist, Sarah Jarosz, appearing on her three critically acclaimed albums, Song Up In Her Head, Follow Me Down and Build Me Up From Bones, as well as being featured on her Grammy-nominated instrumental, Mansinneedof. Alex released his debut album Prelude in 2010, featuring Mike Marshall, Grant Gordy and Paul Kowert, along with special guests Bela Fleck and Noam Pikelny. In reference to Alex’s playing on the album, David Grisman says “[Alex] plays with wit, authority and soulfulness belying his years. In my opinion, he's destined to be one of the fiddle giants of the 21st century.”
