You'd have an easier time listing their not-mind-blowing (heyday) songs. There's a reason Julian Cope considers "TV As Eyes" to be his favourite album-opener.
The 2012 single "PROPHECY" returns the band to their circa-1979 style with arguably better results. It sounds like if Half Machine Lip Moves was recorded in a proper studio as opposed to Damon's living room. Probably one of Helios' best songs in years as well.
Fans and critics alike raved over Feel it Like a Scientist, the band's 2014 comeback.
Epic Riff: Helios was inspired by the likes of Black Sabbath, Psychedelic Rock and Punk Rock, so practically every riff was this. Basically anything from Half Machine Lip Moves, Blood on the Moon, Third from the Sun, and Feel it Like a Scientist, plus "Danger Zone".
Fanon Discontinuity: Fans generally ignore the albums without Helios. That includes The Visitation and anything between Chronicles and Retro Transmission.
