Here's the thing. He said he liked Marvo Ging, Hold Tight London and Surface to Air (he's got style). I think Surrender is going to have the most songs with that type of groove.
Here's another option. Go to iTunes (or wherever) and check out the following songs: The Private Psychedelic Reel, The Sunshine Underground, The Test, and The Pills Won't Help You Now. Let us know which you like and we can think about this some more.
Whirly and some others said it best. You can't go wrong with any of their albums and you'll probably get hooked pretty easily.
Also, they do have a singles collection which has some killer tracks. It won't give you the complete album experience like, say, We Are The Night, but it will give you an overview of the ChemBros' progression from 93-03.
Just let us know which way you go and what you end up liking the best.
