Simms went on to become an independent solo artist, releasing 3 EPs and several singles and music videos, before signing with Sumerian Records in 2019.

Simms was the front woman and songwriter/guitarist for the band Automatic Loveletter from 2006 to 2011, releasing four EPs and two full-length albums before their disbandment in late 2011.

[1] Automatic Loveletter was formed with Simms on guitar and lead vocals, Daniel Currier on drums, and brother Tommy Simms playing bass and producing, with bassist Sean Noll sitting in on occasion in Tommy's home studio in the Tampa Bay area.

Signed by Allison Hagendorf, the host of Fuse TV's The Pop TV Show, then working at Epic Records, Simms went on to form Automatic Loveletter while Epic struggled with the Sony BMG 2005 Payola Scandal and internal problems finally dropping over 70 bands in 2007.

Simms took her songbook to Matt Squire and narrowed down the tunes and crafted them to fit together, sometimes taking songs in entirely new directions.

Instead, Simms submitted a fan favorite "Black Ink Revenge" which was rejected several times for rewrite until it became "My Goodbye" one of the tracks off the upcoming Sony release.

"My Goodbye", "The Day that Saved Us", and "Hush (New Version)" were quickly released as another self-titled EP just before the final chapter with Epic Records when they fired all the members except Daniel Currier before the first headlining tour.

Despite this devastating setback, the new hired guys pulled together and stayed on to complete the tour, and Automatic Loveletter went on to sell out venues like the Knitting Factory in LA and San Francisco.

In 2011, Simms released an entirely acoustic album through Paper + Plastick Records called "The Kids Will Take Their Monsters On".

In 2019, Simms announced her signing to Sumerian Records and released single "Bad Love" to kick off the Rockstar Energy Disrupt 2019 Tour in August 2019.

Announced on February 19, 2021, Simms has officially rebranded herself, now going as Lilith Czar, and her debut album with Sumerian Records 'Created From Filth And Dust' which released on April 23, 2021.

Made available on iTunes and CD Shortly after finishing The Voice, Simms was signed by CeeLo Green, her coach on the show.

Her debut single "Wild Child" was released on December 11, 2012,[7] followed by a music video in April 2013, for which Cee Lo Green is an executive producer.

The recording and development of the album was primarily funded by PledgeMusic,[10] A music video for the EP's fourth track, "End of the World", was released May 2015.

In February 2021, Simms announced her new name Lilith Czar, along with a new album called Created from Filth and Dust, released on April 23, 2021.
