Growing up in Altadena, California, Greg and Thom Moore shared a room for 15 years, in which they amassed a tiny collection of LP's stolen from their parents. Over time, the Cowsills, Bee Gees, and the Beatles gave way to Thomas Dolby, the Cocteau Twins, and the Incredible String Band. On May 5, 2003, the Moore Brothers released their second album, On and Out, which was released on Amazing Grease Records. It features the same production and rhythm section team as their debut album, Colossal Small. Producer Jon Erickson supplies the bass while Andrew Borger (Norah Jones, Preston School of Industry, Tom Waits) plays drums. Like its predecessor, it features a wide array of styles and moods that showcase the Brother's close harmony singing and their individual talents as well. The themes explored on the album include problematic relationships, marriage, and nuclear explosions.
2003 also saw the release of an album Greg made in collaboration with Lois Maffeo, entitled Owl and the Pussycat, released on Kill Rock Stars. Thom has been singing with his acapella folk duo, Chicken On a Raft, and writing songs with Nedelle, whose debut album, Republic of Two, was released in the spring of 2003 on Kimchee Records.
