Katie began singing in church choir in her home town of Asbury Park, NJ, and continued in high school talent shows and the Vassar College Madrigal Singers and chorus. She made her way to San Francisco in 1978, singing (and playing keyboards) in bands like Barry Beam, Verbal Abuse, and Thump Thump Thump. It was with these groups that she met the musicians who would later join her in creating the prototype party bands Zasu Pitts Memorial Orchestra, which won a Bammy for Best Independent Album, and Big Bang Beat.
Katie has always been recruited by local dance record producers to sing on their latest tracks. She soon found herself touring discos and clubs everywhere, performing hi-NRG hits with Megatone Records groups SFX and Modern Rocketry. More information about her records can be found here.
As the ‘80s drew to a close, Katie began new collaborations with her husband, record producer and musician Morey G. In a musical revue called Morey Goldstein's Cavalcade of Stars, Katie got rave reviews for her portrayal of Karen Carpenter. This led the two to develop, with writer/director Tom Ross, A Karen Carpenter Christmas, which ran in San Francisco and later Seattle until 2002. In 2008, Katie and Tom Ross also collaborated on The Coverlettes Cover Christmas, which enjoyed two seasons at the Aurora Theatre in Berkeley. Sadly, Morey died of brain cancer in July, 2008; this was to have been his last show.
Throughout the 1990s until 2008, Katie continued to sing with Big Bang Beat. She performs now with R&B group The Soul Delights, the jazz-influenced Randy Craig Trip, and girl group The Coverlettes. Over the years she has accompanied musical acts such as Ronnie Spector, Bonnie Raitt, The Doobie Brothers, and members of The Grateful Dead. Katie has also performed at hundreds of special corporate events and conventions across the globe.
The high point of 2009 was singing “Blowing In The Wind” with the Terry Haggerty Band for 77,000 music fans in Golden Gate Park for West Fest ‘09.
In 2012 Katie released her first solo album, "Katie Guthorn, Why Not Smile?", a collection of jazz and pop covers produced by Tim Haggerty.
