Ian Anderson's solo career will be celebrated with a new 10-disc vinyl box set 8314 Boxed, due on Aug. 23. Pre-ordering is already underway. An official trailer for the box set is below.

Among the highlights are two sequels to Jethro Tull's prog cornerstone Thick as a Brick. 8314 Boxed will include a 2LP reissue of 2012's Thick as a Brick 2 with a special etching on Side D and a half-speed vinyl remaster of 2014's Homo Erraticus, which again followed the fictional character Gerald Bostock.

Three of Anderson's solo albums have never before appeared on vinyl: 1995's Divinities: Twelve Dances with God, 2000's The Secret Language of Birds and 2003's Rupi's Dance. The track listing for a disc titled Roaming in the Gloaming featuring unreleased live recordings from 1995-2007 is also below. 8314 Boxed is rounded out by a 96-page book with a foreword from Anderson and exclusive new liner notes and photographs.

"Since 1983, I have made a few solo albums, not as dissatisfaction with fellow musicians or the group identity but usually just to try something a bit different – whether sonically, stylistically or in terms of instrumental line-up," Anderson said in an official statement.

"These records all stand out for me as being quite different from each other and in some ways demonstrate a broader depth of my songwriting," he added. "The flute instrumental Divinities record is one of my favorites to this day."

The Secret Language of Birds became a Top 30 U.S. hit in 2000, while fans who remained interested in Bostock's fate pushed Thick as a Brick 2 to the Top 40 in the U.K. Homo Erraticus fared even better, hitting No. 14 on the U.K. chart in 2014. Anderson released Thick as a Brick: Live in Iceland later in the same year.
