What is some of the best music that I have never heard of-artists or albums?

I love The pierces, Susan Cagle, (French Camille and Cali), Jem.. Heard of Poe Plumb, Courtney jaye... Give me unheard of gems (no pun). Pop, pop/Rock Light rock, accustic, low-fi, trip-hop, maybe symphonic rock like verve, upbeat folk... I want to weep from the glory of it's musicality! (am I overstated?)
