Bradley gained fame in 2013 as a contestant on season eight of America's Got Talent, during which she advanced to the finals by performing her arrangements of popular songs including "Believe".

A full-length album scheduled for 2018 was scrapped; after a seven-month break, Bradley and Dean released the EP Losing Ground Vol.

Her father, Paul Miller,[5] was the worship leader at the family's church; he was practicing vocal scales in the car while on the way to perform services when four-year-old Cami started singing along.

[6] Cami Miller began learning the piano by age seven,[7] and started writing songs at ten, though she later called those efforts terrible.

[8] Her early style was influenced by a wide range of music, including artists Christina Aguilera and Natalie Cole, and soundtracks to Disney films.

[9] Miller began performing her songs during her teen years;[6] the week before she turned 18, she won a car by finishing first in the Spring 2006 season of the local Gimme the MIKE competition.

[17] Seas comprises seven songs including "This Ocean", a duet with her younger brother Ryan Miller,[18] one-half of the indie duo the Rustics.

[20] Instead, she sang an a cappella version of "Somewhere Over the Rainbow", prompting the judges to put her through to the Las Vegas round; there, she performed "Summertime" and advanced to the live shows.

Also in 2020, The Sweeplings uploaded several official music videos to their YouTube channel, including "In Between" in January,[44] "Bleed Me White" in March,[45] and "I Won't Go" in August.

[47] Carmen Jane makes songs that feature a different tone than her other work,[43] a more experimental "dark pop" sound reminiscent of Billie Eilish.

[50] AllMusic wrote that songs composed by Bradley and Dean reveal "a penchant for haunting, tender harmonies and a roots-inspired sound that bears similarities to The Civil Wars.

[53] In its review of Sleepwalking, Atwood Magazine wrote, "Cami Bradley's breathtaking voice leads with pain and passion, charged with a poignant edge that is as biting as it is bitten.
