Tally Hall (sometimes stylized as tallyhall) is an American rock band formed in Ann Arbor, Michigan, in December 2002, and publicly active until the conclusion of their Good & Evil tour in 2011.

Media, who previously helped finance and nationally distribute their debut studio album, Marvin's Marvelous Mechanical Museum on October 24, 2005.

Some Tally Hall members (Rob Cantor, Joe Hawley, and Zubin Sedghi) also provided the vocals and music for all of the songs in Happy Monster Band, a children's television series that aired on Playhouse Disney.

Andrew Horowitz, born in Warren, New Jersey,[3] began writing songs when he was eight years old and studied composition at the University of Michigan.

At the same time, fellow Michigan student Joe Hawley was studying film, and had formed the sketch comedy group AnonyMous.

Before the release however, Gallagher suddenly left the group in May of that year, being replaced by Ross Federman, whom Hawley knew from high school.

On October 24, 2005, the band released their debut studio album, Marvin's Marvelous Mechanical Museum, with violinist Jeremy Kittel contributing strings.

[11] The band worked on several projects after the completion of Marvin's Marvelous Mechanical Museum, including covering the song "Smile Like You Mean It" by The Killers for the sixth The O.C.

On September 9, 2009, Tally Hall released the song "Light & Night", featuring Nellie McKay, as a free download when customers of Walmart purchased The Magician's Elephant by Kate DiCamillo, published the same day.

[17] Around the same time, the band released a cover of the Flo Rida song "Club Can't Handle Me", with Casey Shea on guest vocals.

A sequel titled etudes II was released in April 2019, featuring compositions written in 2005 while he attended the University of Michigan.

In May 2020, he started a weekly Instagram livestream series titled Keep Up The Good Work, featuring interchanging guests such as Federman and Sedghi.

Hawley has been vague regarding the overarching story behind the album, at one point citing the September 11 attacks as inspiration, however this has been contradicted in other interviews.

In addition, he has made several viral videos on YouTube, including "Shia LaBeouf", "Christian Bale Is At Your Party",[29] and "29 Celebrity Impressions, 1 Original Song".

On November 11, 2020, a truncated version of the original album was uploaded to Apple Music and Spotify, removing the 13th and final track (a cover of rock band Jefferson Airplane's "White Rabbit").

Hawley has promised it on social media and Sedghi has jokingly stated that they would return if they received "thirty or forty million listeners a month" via a message for Spotify Wrapped.

The group made several movies of humorous skits and music videos, the latter containing Tally Hall songs such as "Banana Man", which resulted in significant publicity on the website Albino Blacksheep.

They have appeared on Fearless Music several times, playing songs such as "Be Born", "Ruler of Everything", "Misery Fell", "Good Day", and "Banana Man".

In July 2014, band member Rob Cantor released a video in which he appeared to perform his song "Perfect" by singing spot-on impressions of 29 celebrities.
