'The Astonishing' also starts atop the Hard Rock Albums chart.
Previously, the band peaked as high as No. 2 with 2009's Black Clouds & Silver Linings and 2011's A Dramatic Turn of Events. The Astonishing also marks Dream Theater's third No. 1 on Hard Rock Albums, following Black Clouds & Silver Linings and its 2013 self-titled record.
Both the Top Rock Albums and Hard Rock Albums charts began in 2006, by which point Dream Theater was already eight records-deep into its discography. On the Billboard 200, the act reached its best rank (No. 6) with Black Clouds & Silver Linings. The new album starts at No. 11.
