Thin Lizzy.
Formed by Charismatic bass player/singer/songwriter Phil Lynott, Thin Lizzy were around from 1969 until disbanding after their final tour in 1983, which this recording is the first concert from that tour. Lynott died in 1986 as the band were talking about getting back together, but his death smashed any idea of a reunion since Thin Lizzy was, for all intents and purposes, Phil Lynott.
They were a very influential band in the area of Heavy Metal and Hard Rock and numerous bands cite them as an inspiration for their style. They've gone on to achieve cult status in recent years and all their albums have been reissued several times over the years.
If you're not familiar with them, just know they aren't one of the more quiet or sedate bands you'll be encountering any time soon.
oh yeah . .
just in case.
