Heartland

I heard the cover Maryslim did of "This Corrosion" and kinda liked the music apart from the guest vocalist who spoilt the whole thing trying to sing deeper than is in his range. Anyway, I came across this other song by Maryslim and actually really like it. Not heard anything else they have done but anyone have any feedback about this band and if they is any good ?? http://www.youtube.com/watch?v=66w709MKgKc
