then-unreleased song "Such Great Heights". Rather than being included on an Iron & Wine release, the track was initially included as a b-side of the original version by The Postal Service. It was later included on the B-sides and rarities album, Around the Well. He then followed up on his debut album in 2003 with The Sea & The Rhythm, an EP containing other home-recorded tracks with a similar style to the songs on the debut. Beam's second full-length album, Our Endless Numbered Days (2004), was recorded in a professional studio with a significant increase in fidelity. Produced in Chicago by Brian Deck, the focus was still on acoustic material, but the inclusion of other band members gave rise to a slightly different sound. That same year, he recorded the song "The Trapeze Swinger" for the film In Good Company, and had his version of "Such Great Heights" featured in an advertisement for M&M's and in the film and soundtrack for Garden State. This version was later used in a 2006 Ask.com advertisement, and eventually released as a single in 2006 backed with recordings of "The Trapeze Swinger" and "Naked as We Came" made for Radio Vienna. In February 2005, he released an EP entitled Woman King, which expanded on the sounds of his previous LP with the addition of electric guitars. Each track features a spiritual female figure, and had subtle Biblical undertones. The EP In the Reins, a collaboration with the Arizona-based rock band Calexico, was released in September 2005. Beam wrote all of the EP's songs years earlier, but Calexico added their trademark fusion of southwestern rock, traditional Mexican music and jazz to the songs' arrangements. Several tracks, most notably, "Burn That Broken Bed", feature brass instruments, a first for Beam's music. The third full-length Iron & Wine album, entitled The Shepherd's Dog, was released September 25, 2007. This album was voted one of the ten best of 2007 by Paste magazine. Contributors included Joey Burns and Paul Niehaus of Calexico, as well as jazz musicians Matt Lux and Bob Burger. When asked to describe the album to The Independent, Beam remarked that "it's not a political propaganda record, but it's definitely inspired by political confusion, because I was really taken aback when Bush got reelected." Beam has released most of his music on iTunes, including several exclusive EPs. The Iron & Wine iTunes Exclusive EP features
