Ann Marie Calhoun

Ann Marie Calhoun ( Simpson; born May 26, 1979) is an American classically trained violinist who has performed as a bluegrass and rock musician in a number of prominent acts, including Jethro Tull, Steve Vai, Widespread Panic, Dave Matthews Band, Ringo Starr, A.R. Rahman and Mick Jagger's SuperHeavy.

She has closely collaborated with Hans Zimmer on numerous film scores, including Sherlock Holmes, Interstellar, 12 Years a Slave, The Lone Ranger, The Little Prince, Man of Steel, and Captain Phillips.

She is the sister of violinist Mary Simpson.

She was born Ann Marie Simpson in 1979 in Virginia to a "hillbilly dad", a "documented descendant of Pocahontas", who plays banjo; and a "Chinese mom", who was a classically trained pianist.

Her brothers play guitar and her sister, Mary Simpson, is an accomplished bluegrass fiddler.

Simpson attended the University of Virginia where she double-majored in Music and Biology, graduating in the class of 2001.

While studying there she shared her bluegrass fiddle talents with Walker's Run in Charlottesville, Virginia.

From 2001 to 2003, she was part of the bluegrass fusion ensemble Old School Freight Train.

She also takes part in Gary Ruley and Mule Train with other members of Walker's Run.

Before dedicating herself completely to her musical career, Simpson taught science and directed the strings program at Woodberry Forest School, in Madison County, Virginia.

She is "taking a leave from this school to pursue music."

She was previously married to Brian Calhoun from 2002–2013.

Simpson began taking violin lessons at the age of three.

As she says: "I actually don't remember learning how to play, because I started when I was three. I feel like I've always known."

The first hint of her talent came at the age of four when Simpson and her father were watching a Washington Redskins game on television.

After their marching band played "Hail to the Redskins", he suddenly heard it again, only this time on the violin.

"She picked it up through her ears, and it came out through her fingers instantly. I knew she had a gift then."

Simpson began playing bluegrass music with her siblings in the Simpson Family Band.

As her father states: "When she was 14, I started taking her to the fiddle contests, and she won just about every one."

Simpson attended Lake Braddock High School in Burke, Virginia, close to Washington, D.C. As a teenager, she was a youth fellow with the National Symphony Orchestra, a program that took her weekly to the Kennedy Center and provided private lessons with the National Symphony Orchestra's violinist, William Haroutounian.

In 2004, Simpson recorded the violins on the album Stand Up for the Dave Matthews Band.

In 2005 she toured Italy with the North African/American band, Kantara, which performed Arab-Appalachian music.

In 2006 Simpson was invited to tour with the progressive rock band, Jethro Tull, as a guest soloist.

She admitted: "I had to Google 'Ian Anderson' when he first contacted me."

Anderson later said of Simpson: "Unlike many of her fiddlin' friends from the classical world, Ann Marie has cultivated considerable improvisational abilities but still retains her music theory and the ability to play set parts and orchestrations."

In 2007, Simpson became a member of Steve Vai's band, String Theories.

The band began a world tour in June 2007.

Simpson received a gold sales award for her participation in Vai's "Where the Wild Things Are" DVD.

Her performance with Vai on "Now We Run", was nominated for a Grammy Award in the category of "Best Instrumental Rock Group Performance".

Vai commented about her performance at that event: "She should have been the one who had a full performance on the show, because she would have stunned people."

At the 50th Grammy Awards on February 10, 2008, Simpson was the winner of the "My Grammy Moment" contest, and played live with the Foo Fighters during the broadcast.

In late February 2008, she recorded with The Hooters and played as a special guest with the band the Disco Biscuits.

Later that year, Simpson performed multiple times as a special guest with the bands Switchfoot and Widespread Panic, and then performed with Ringo Starr on Larry King Live, The Late Late Show with Craig Ferguson, and at the Los Angeles House of Blues.

2009 saw Simpson perform with the "First Lady of France", Carla Bruni, along with Josh Groban and Aretha Franklin, at Radio City Music Hall to celebrate Mandela Day.

Simpson appeared several times with Bon Jovi, including a Christmas performance at the White House for President Barack Obama.

Simpson has toured as a featured soloist with Yanni.

Simpson collaborated with Hans Zimmer, as a featured soloist and contributing writer on the film score for the 2009 film Sherlock Holmes, directed by Guy Ritchie.

On January 13, 2010, she performed for Ringo Starr with Ben Harper and the Relentless7 on The Daily Show to promote Starr's new album, Y Not.

She again played with them, with the addition of Joan Osborne, on January 14, 2010, for a performance at the Metropolitan Museum of Art, in New York City (which was recorded for the 2010 PBS show, Live from the Artists Den).

In 2016 she married Incubus guitarist Mike Einziger, with whom she has twin daughters, Talulah and Penelope, born in 2017.
