Good music!!!
Pardon the comparison (and I mean it as a compliment), but it reminds me a lot of the band "Live"...
My favorite song by Live, "Lakini's Juice" from "Secret Samadhi":
One of their most famous (well known) songs, "Lightening Crashes":
Best of luck to your friends band - they are really good!
If they have some YouTube vids, please post them up (or suggest that they do so).
