The Halo Effect coalesced in 2020 motivated by the 1990s “Gothenburg sound” that pioneered the melodic death metal genre. The band’s name comes from the song of the same name off Rush’s 2012 album, Clockwork Angels.

Founded by five friends whose previous careers had intersected at different times in the band In Flames. Jesper Strömblad was a founding member of In Flames in 1990, and in 1993 Mikael Stanne (who founded the band Dark Tranquility and remains its sole founding member today) worked as a session vocalist on In Flames' demo tape and debut album. Niclas Engelin and Peter Iwers joined In Flames in 1997, and Daniel Svensson joined In Flames in 1998 after Engelin quit. Subsequently, Strömblad, Iwers, and Daniel Svensson played together in In Flames for over 20 years by the time Strömblad left In Flames in 2010.

Mikael Stanne – Lead Vocals (2021–present)
Niclas Engelin – Lead Guitar (2021–present)
Jesper Strömblad – Rhythm Guitar (2021–present)
