Stranger, Kozelek commented that he's "never heard from Modest Mouse" as to what they think of the record. In 2006, Kozelek was invited by Toronto indie rock label Paper Bag Records to exclusively contribute to their See You on the Moon! Songs for Kids of All Ages compilation with his original song "Leo and Luna." Then in November 2006, Kozelek released a live album titled Little Drummer Boy Live. Kozelek returned in 2008 with the release of Sun Kil Moon's third album April. The album features 11 brand new recordings, including guest vocal contributions by Ben Gibbard, Will Oldham and Eric Pollard. The release of the new album also brought the re-issue of Nights of Passed Over, a 256-page, hard-cover book of all the lyrics to Kozelek's solo songs, Red House Painters' songs, and Sun Kil Moon's songs. It also features setlists, handwritten lyrics, and a preface by Kozelek himself. The original edition of this book was released in 2002 in Portugal, and featured all the lyrics up to that point, printed in both English and Portuguese. The updated edition spans to his current Sun Kil Moon days, and the book also includes a 12-track bonus CD titled Nights LP, featuring live and rare versions of songs dated 1996 to 2007. The edition is sold exclusively on his label's website and is limited to 2,500 copies. On December 9, 2008, Kozelek and Caldo Verde Records issued The Finally LP, a CD collection of 10 unreleased tracks, including covers of songs by Stephen Sondheim, Will Oldham, Hüsker Dü, and Low among others, as well as two previously unreleased instrumentals. Two newly recorded live albums, Find Me, Ruben Olivares: Live in Spain and Lost Verses Live, followed in spring 2009. On April 23, 2010, the release of Sun Kil Moon's fourth album, Admiral Fell Promises, was announced. The album was released on July 13, 2010. A documentary film titled Mark Kozelek: On Tour was released via Caldo Verde Records on August 16, 2011. The movie was filmed during portions Mark Kozelek's European/North American tours of 2010 and early 2011. Sun Kil Moon's fifth album, Among the Leaves, was released on Caldo Verde Records on May 29, 2012.
