Sidney Matthew Sweet (born October 6, 1964) is an American alternative rock/power pop singer-songwriter and musician who was part of the burgeoning music scene in Athens, Georgia, during the 1980s before gaining commercial success in the 1990s as a solo artist.

In addition, he formed another duo, The Buzz of Delight, with Oh-OK drummer David Pierce, releasing an EP, Sound Castles, in 1984 on DB Records.

This marked a personal and professional low period as his record company lost interest and his marriage failed.

In 1993, Sweet released Altered Beast, an album which drew mixed reactions with its intense and brooding tracks (such as "Someone to Pull the Trigger" and "Knowing People").

The album itself fared better commercially, and even made it onto Entertainment Weekly critic David Browne's year's-best list.

In 1997, Sweet released Blue Sky on Mars, a new-wave album which featured the synth-laden singles "Where You Get Love" and "Come to California".

In 1998 his version of Walter Egan's Magnet and Steel was recorded on the Sabrina The Teenage Witch album with Lindsey Buckingham on guitar.

In 1999, Sweet released In Reverse, a psychedelic album which featured Wall of Sound singles "What Matters" and "Trade Places".

[16] Also that year, Sweet contributed an essay for the Mark Dillon book Fifty Sides of the Beach Boys on the 1967 song "Wonderful".

[21][22] Sweet and his wife Lisa were also research consultants for the Tim Burton film Big Eyes, a biography on painter Margaret Keane.

[26] In 2017, Sweet released Tomorrow Forever,[27][1] a rootsy album funded entirely by fans on Kickstarter; over the course of one month in 2014, the project exceeded its $32,000 goal by 75% from fewer than 800 backers.

Also that year, Sweet was paid tribute in the compilation album, "Altered Sweet", which included artists such as Lisa Mychols, Andy Reed, Greg Pope, Nick Bertling, Fireking, Chris Richards & The Subtractions, simple friend, Michael Simmons, Gretchen's Wheel, The Well Wishers, Elvyn, Pop Co-Op, Stabby Robot, Lannie Flowers, Stereo Tiger, Michael Carpenter, Phil Ajjarapu, CokeRoque, Donny Brown, Nick Piunti, Paranoid Lovesick, Trolley, Keith Klingensmith, Arvidson & Butterflies, Robyn Gibson and Popdudes.
