Mr. A–Z

Mr. A–Z is the second album by the American singer-songwriter Jason Mraz, released on July 26, 2005. It is the follow-up to his first album Waiting for My Rocket to Come, released in 2002. Even with mixed reviews, it was a moderate commercial success and debuted at number 5 on Billboard ' s Top 200 albums chart. It was recognized for mixing many different genres of music together.

It was nominated by the Recording Academy for best engineered album, and the producer Steve Lillywhite, who previously worked with U2, Dave Matthews Band and The Rolling Stones, won for Producer of the Year, but not for his work on Mr. A–Z. The name of the album is a play on the artist's surname, "Mraz".

An opera solo performed by Mraz himself can be found on the track "Mr. Curiosity". In March 2010, this song charted in Germany after it had been performed by Lena Meyer-Landrut in the talent show contest Unser Star für Oslo (Our Star for Oslo), reaching a peak position of number 44.

Formats
In the United States and Europe, the album was released both as a CD and as a DualDisc. The DualDisc version has enhanced packaging and an extra booklet.

In July 2022, the album was reissued for the first time on vinyl, pressed to 2 LPs on both black and limited edition translucent blue vinyl versions.
