Big Bang Theory is the fifteenth studio album and the first covers album by the band Styx, released in 2005. It consists of cover versions of classic rock songs.
Origin
In 2004, Styx performed a cover of the Beatles song "I Am the Walrus" at Eric Clapton's Crossroads Festival, where the song was received so well that it was released as a single, reaching the Top 10 in the Mediabase Classic Rock charts.[4] The video featured original bassist Chuck Panozzo as the "eggman". The single's success resulted in the band recording this album of cover songs. The album reached #46 on the Billboard Top 200 Albums, Styx's highest charting album in 14 years. The single "I Am The Walrus" reached a high of number 27 on the Billboard Heritage Rock Chart.
