Jason Lytle (/ˈlaɪtəl/ LY-təl; born March 26, 1969) is an American musician best known for his work in the indie rock group Grandaddy.

[2] While laid up with a career-ending ACL injury, he started to play music again, writing songs and eventually setting up a home studio.

After spending years on the road, Lytle grew tired of the rock and roll lifestyle and recorded much of the band's fourth album, Just Like the Fambly Cat, on his own.

In December 2005, six months prior to the release of Just Like the Fambly Cat, the band decided to break up: the reasons included elusive mainstream success, despite widespread critical acclaim, and lack of money.

[2] Mid-2006 saw Lytle briefly touring the U.S. in support of The Fambly Cat, playing new arrangements of Grandaddy songs as a duo with Rusty Miller of the band Jackpot.

On December 7, 2009, Lytle independently released an EP of seven improvised piano recordings as a "Merry X-mas" gift to fans through his website on Bandcamp.
