Pink Floyd assembled one of rock's sturdiest concept albums with 'The Wall,' but Jethro Tull created some classic masonry of its own with 'Thick as a Brick' -- and we're pitting the two title tracks against each other in this edition of Clash of the Titans.

Tull struck first, releasing 'Thick as a Brick' in March of 1972. Written as a sort of goof on prog-rock bombast, the album consists of one song (split into halves, a necessity during the vinyl era) presented as a musical adaptation of an eight-year-old's poem. If it was a joke, plenty of people got it -- 'Brick' topped the album charts and, along with the previous year's 'Aqualung,' went down as one of the group's signature works.

Seven years later, Pink Floyd erected their 'Wall,' a two-LP musical journey about the tortured life of a man named Pink, who suffers through a miserable childhood, adulthood, and marriage after the death of his father in World War II. A massive success in the U.S. as well as the band's native U.K., the album proved thought-provoking enough for Floyd fans as well as radio-friendly enough for the Top 40, where 'Another Brick in the Wall (Part 2)' topped the charts in Britain and the States.

The creative principals behind both records have returned to these albums repeatedly over the years, with Tull's Ian Anderson crafting a 'Brick' sequel in 2012 and performing both albums in their entirety live in 2012; Floyd's Roger Waters, meanwhile, has mounted many live productions of 'The Wall,' recording a 1990 performance at the Berlin Wall for a live album and filming a later 'Wall Live' world tour.

So which ‘Brick’ gets your vote in this Clash of the Titans matchup? Check them both out below, and remember: you can cast a ballot once an hour between now and when voting ends on Sunday, Sept. 7, at 11:59PM Eastern.
