Era Vulgaris had sold 198,000 copies in the US, and 521,000 copies worldwide before falling off the charts. The US sales are a decline from their previous album, as Lullabies to Paralyze, had sold 342,000 copies in the US by March 2007.[21] Neither album achieved the commercial success of the band's 2002 release, Songs for the Deaf, which had sold 986,000 copies in the US alone as of June 2007.[22]
