Parker's first solo album Sunlight Tonight was released in November 2018.

The Whigs were formed in 2002 by Parker Gispert, Julian Dorio, and Hank Sullivant in Athens, Georgia.

The band toured the world consistently from 2005-2015 as headliners and as openers for the likes of Kings of Leon, Black Keys, Black Rebel Motorcycle Club, and Jason Isbell.

Produced, Mixed, and Engineered by Grammy Award winner Emery Dobyns (Antony and The Johnsons, Patti Smith), the album includes contributions from Patrick Carney (Black Keys), Sol Seppy (Sparklehorse), Samul Dixon (Adele), and Faye Webster among others.

Parker co-wrote "Private Public Breakdown" with Alice Cooper and producer Bob Ezrin which appears on the Alice Cooper album Paranormal.
