Run by two main members, Dylan Thomas More and Jared Louche, and having additional members with backgrounds from many interesting industrial band, Chemlab have toured with bunch of "well-known names" in the industrial metal genre including White Zombie, KMFDM and Nine Inch Nails. But I assume they more or less stayed in US side of the Atlantic.
The old albums sounds really relevant still today (it's not that common with 15 years old industrial albums). There's something catchy in their sound, a bit similar as Pitchshifter in their prime. Here's a sample from their debut album Burn Out at the Hydrogen Bar released 1993.
