Question: Keep It Hid is the debut solo album by the American blues-rock musician Dan Auerbach of the Black Keys, the final track "Goin' Home" was included in the soundtrack of the 2009 film "Up in the Air", an American comedy-drama film, directed by who?
Context: The Big Come Up is the debut studio album by the American rock duo The Black Keys, released in 2002 on Alive Records.  The blues-rock duo includes singer and guitarist, Dan Auerbach, and drummer, Patrick Carney.  The album was created in Akron, Ohio, also known as the Rubber City.  As the two began to grow up, they realized that rubber companies, such as Goodyear, were a dying industry.  They knew they were not guaranteed an automatic job by achieving a college degree, so the two dropped out of college to pursue their musical career.  They began producing "The Big Come Up" in their basement.  Carney and Auerbach recorded the album in Carney's basement, using two microphones bought off of eBay.  They recorded their album on an 8-track tape recorder because there was no longer a need for a needle, it did not break or shatter, and it could be played in the car.  The cheap equipment gave the album a grainy, lo-fi sound, almost as if it had been recorded in the 1960s.  This made their album sound unprofessional, but in turn, gave them a sense of authenticity that was largely based on other popular rock artists, such as The White Stripes.  The record contained thirteen songs.  Eight of them were their own original tracks, and five were cover songs.  These cover songs included covers of Muddy Waters, Junior Kimbrough, R.L. Burnside.  They also released an EP that included covers of the blues song "Leaving' Trunk" and the Beatles' song "She Said, She Said".  The song "I'll Be Your Man" was used as the theme song for the HBO series "Hung".  "I'll Be Your Man" also appeared on the FX series "Rescue Me".  Alive Records re-presses this album regularly, often several times a year on different colored vinyl or with altered sleeve artwork.  These are usually marketed as limited editions.  Alive Records had released "The Big Come Up" on vinyl on at least 14 separate occasions, opening themselves up to criticism, particularly in regard to the marketing term "limited edition".

The band's raw blues rock sound draws heavily from Auerbach's blues influences, including Junior Kimbrough, Howlin' Wolf, and Robert Johnson. Waiting on a Song is the second studio album by American musician Dan Auerbach.  The album was released on June 2, 2017, and is the first release from Easy Eye Sound, Auerbach's label.
