As the one reviewer on Prog Archives, Sularetal, has suggested, ISIS' Live 1 will mostly appeal to post rock lovers and established fans of the band. I generally adore ISIS' live albums, unlike live albums from most bands. I'm giving Live 1 three and a half stars. The sound quality is just fair, but that's not surprising considering Live 1 was self-released. Aaron Harris has obviously been a fantastic drummer since the band's beginnings. There is almost no singing, but vocal quality was never a priority for ISIS.
I won't single out individual songs for merit, even though ISIS was definitely not your run of the mill post rock band from the start. Their music became increasingly more varied and interesting over time. I would call ISIS' first live release more of an EP than an album. It's only four songs lasting a total of 40 minutes. However, that's just semantics. Over all, this is a very listenable 40 minutes.
