"Mythology" contains four discs housed in a 5 3/4 X 7 5/8 X 7/16 box, with each disc spotlighting a different Gibb brother, including one disc dedicated to Andy. The songs were chosen by Barry, Robin, Maurice"s widow Yvonne (and their children Adam and Samantha), and Andy"s daughter Peta. "Mythology" also features a collection of family photos, many never-before published, along with tributes from artists such as George Martin, Brian Wilson, Elton John, Graham Nash, and the band"s longtime manager Robert Stigwood. Spanning the Bee Gees" five-decade career, the set"s 81 tracks touch on several of the group"s best-known hits. The final disc spotlights Andy Gibb, who worked with his brothers throughout his career, before his death in 1988 at the age of 30. Notably, Andy"s first 3 singles all went to #1 in the U.S., a feat that had never been accomplished before. "Mythology" also marks the debut of "Arrow Through The Heart," a song Andy recorded shortly before his death that was intended for a comeback album.
