Not as vastly wide-ranging as other albums in the FSOL canon, but still worth a listen to; and worth remebering that when you hear this it was truly at the cutting edge to broadcast your concert from your studio - this dates from 1995, for goodness sake!
Listen to this an hear a bit of musical history - the album title says it all. Lifeforms would probably get you to appreciate the vast tonescapes that FSOL can create in your mind, ISDN creates images that are slightly smaller, but just as visceral.
