Opening with the sound of glass shattering, Glass Houses has more of a hard rock feel than Joel's previous albums. The cover shows Joel poised to throw a rock through the two-story window of his real-life waterfront glass house in Oyster Bay. This alludes to the adage that "people in glass houses shouldn't throw stones."

Released on March 10, 1980. It features Joel's first song to peak at #1 on Billboard"  Pop Singles chart, "It's Still Rock and Roll to Me." The album topped the Pop Albums chart for six weeks and was ranked number 4 on Billboard's 1980 year-end album chart.
