Some releases are credited to "Nick Cave & the Bad Seeds" others are "Nick Cave and the Bad Seeds." This is intentional on the part of the editors and matches the various releases. If you need to group them or normalize them in your own collection, use the %albumartistsort% variable (or something like "$if2(%albumartistsort%,%albumartist%,%artistsort%,%artist%)") in your tagger.
Do not make arbitrary edits to the artist credits unless you can prove that your edit matches the release.
Nick Cave and the Bad Seeds are an Australian alternative rock band that was formed in Melbourne in 1983 by lead singer Nick Cave, multi-instrumentalist Mick Harvey and guitarist Blixa Bargeld. The band has featured international personnel throughout its career and presently consists of Cave, violinist and multi-instrumentalist Warren Ellis, bassist Martyn P. Casey and keyboardist Conway Savage (all four from Australia), keyboard/percussion player Barry Adamson and guitarist George Vjestica (both from the United Kingdom), and drummers Thomas Wydler (Switzerland) and Jim Sclavunos (United States). The band has released fifteen studio albums and completed numerous international tours.
The band was founded after the demise of Cave and Harvey's former group the Birthday Party, the members of which met at a boarding school in Victoria, Australia. Deviating from the noise rock roots of their contemporaries, Nick Cave and the Bad Seeds have produced alternative rock that has been influenced by various genres, such as punk rock, gothic rock, no wave and blues. Their early material—From Her to Eternity (1984), The Firstborn Is Dead (1985), Your Funeral... My Trial (1986) and Tender Prey (1988)—primarily featured a post-punk sound. The band has progressively incorporated other songwriting elements; for example, the 2008 release Dig, Lazarus, Dig!!! experimented with garage rock, also an influence of the side project Grinderman. Synthesizers and minimal guitar work feature prominently on Push the Sky Away (2013), recorded after the departure of Harvey in 2009.
