Moore announced he had left From First to Last to pursue a solo career. He then launched a Myspace page displaying three demos ("Signal", "Equinox", and "Glow Worm"). This led to Moore's first performance since his leaving From First to Last. On April 7, 2007, alongside harpist Carol Robbins, Moore played several original songs at a local art building. After months of releasing demos via Myspace, Moore played on the Team Sleep Tour with a full band. The tour also featured supporting acts Monster in the Machine and Strata.
Moore made several demo CDs available on this tour, limited to about 30 per show. These CDs were tour exclusive, and were packaged in "baby blue envelopes", each with a unique drawing by Moore or bandmate. In February 2008, Alternative Press Magazine announced the second annual AP Tour, with All Time Low, The Rocket Summer, The Matches, and Forever the Sickest Kids, as well as Sonny Moore. The tour started in Houston, Texas on March 14 and went through North America, ending in Cleveland, Ohio on May 2, with the majority of the shows being sold out.
All bands playing the tour would be featured on the cover of Alternative Press Magazine's annual 100 Bands You Need to Know special, and would be interviewed on the Alternative Press Podcast. During this tour Moore's line-up consisted of Sean Friday on drums, Christopher Null on guitar, and Aaron Rothe on keyboards. On April 7, 2009, he released Gypsyhook EP, a digital EP, which featured three songs and four remixes. Also included was a Japanese version of "Mora" entitled "?? " ("Kaisui"). Physical copies of the EP were available at his shows.
After going on tour with Innerpartysystem and Paper Route and opening for Chiodos on their European tour, Moore performed at Bamboozle on May 2. He performed on Bamboozle Left's Saints and Sinners stage on April 4. He toured with Hollywood Undead in April 2009 performing under the band name Sonny and the Blood Monkeys, with Chris Null (electric guitar), Sean Friday (drums, percussion & beats) and Aaron Rothe (keyboards, synthesizers, programming & turntables) Although no official statement has been given regarding the album, Moore has stated that Bells will no longer be released.
