Alice in Chains' sixth LP is the band's second set to lead all three lists.
Alice in Chains snags its second No. 1 on Billboard's Top Rock Albums, Alternative Albums and Hard Rock Albums charts, as Rainier Fog debuts atop the Sept. 8-dated rankings.
The set starts with 31,000 equivalent album units earned (29,000 in traditional album sales), according to Nielsen Music.
Rainier marks the second set that Alice in Chains has taken to the top of the three charts, following The Devil Put Dinosaurs Here in 2013.
