The bands reign with 'Anthem Of the Peaceful Army' and 'Evolution,' respectively.

Greta Van Fleet and Disturbed launch atop multiple Billboard rock album charts (dated Nov. 3), with the former ruling Top Rock Albums for the first time.

GVF's debut full-length Anthem of the Peaceful Army premieres atop both Top Rock Albums and Hard Rock Albums with 87,000 equivalent album units earned, according to Nielsen Music.

It's the Michiganders' first title to top the former chart and second to lead the latter; the quartet's eight-song EP From the Fires capped the Hard Rock Albums list dated Dec. 2, 2017 (entering with 15,000 units).

Greta Van Fleet is the first band to command Top Rock Albums with a debut LP since Atoms for Peace, with Amok, in March 2013; notably, Atoms for Peace arrived as known entity, a supergroup including Radiohead's Thom Yorke and Red Hot Chili Peppers' Flea, among others, which made its No. 1 debut not unexpected. The last more truly new band, like GVF, to go No. 1 with its first full-length? The Lumineers, with their self-titled album, in February 2013.

Army lead single "When the Curtain Falls" bullets at No. 2 on the Mainstream Rock Songs airplay chart and becomes GVF's first top 10 (12-10) on the all-rock-format Rock Airplay tally (6 million audience impressions).

The track keeping "Curtain" from rising to No. 1 on Mainstream Rock Songs? Six-week leader "Are You Ready," by Disturbed, which debuts atop Alternative Albums with Evolution, as the band's seventh studio set bows with 71,000 units.

Each proper LP of new Disturbed music has debuted at No. 1 on Alternative Albums since 2008, beginning with Indestructible. Evolution is Disturbed's first album of new material since Immortalized, which led the list dated Sept. 12, 2015; it also debuted at No. 1 on the all-genre Billboard 200.
