[Baranxtu]

Well, you almost got it right.

It's simply "Cold Clear Water", as "klares" is derived from "klar" (=clear) and this is the nominative neuter singular form it takes when standing without a definite article.
Compare: kaltes klares Wasser - das kalte klare Wasser

See, you didn't need hints


Okay, looking at my current playlist, try understanding these songs:
Perfekte Welle (for starters)
Symphonie (still doable)
Nur Ein Wort (fu..reaking hard, meguesses)
*German music pimping*
