There are two groups with this name.
AFTERGLOW is a five-piece set from Marseille featuring Reno Ferré on lead guitar, Karim Abdelali on drums, François Festy on keyboards and vocals, Claude Figge on congas and Freud Chaudeaux on lead vocals (Chaudeaux sings in English and sounds a bit like Steve Hoggarth). Deftly avoiding overly simplistic formulas, their style is a savvy combination of hard material from the old guard (SAGA, RUSH) and more modern neo-progsters (PENDRAGON, IQ).

The other band was a psychedelic rock band from Chico, California. The quintet consisted of Larry Alexander (drums), Ron George (bass), Gene Resler (vocals), Roger Swanson (keyboards) & Tony Tecumseh (guitar. The band released a single, eponymous album in 1968 on the MTA label. In 1995, the album was re-released on Sundazed Records.
