Ben Harper help...

Capitol Vaults has just released quite a few, (if not all) of the Ben Harper discography. Where do I start? I have heard of him, but never "heard" anything he did until a song on the radio a few months ago. I was very surprised when the DJ said it was Ben Harper. Of course now I can't find what song it was. I think I have listened to the first 30 seconds, (samples) of every frickin' song he has done, but still don't reconise it.

So, please help me on my journey to Harperland. What albums would give me a good taste of his music?

Thanks!
