Ozma, however, is vaguely comparable to what that's currently successful? Anything? Not really. With few exceptions, you need to ride on some current wave.
I'm a bit late, I know... but i tend to disagree. While there is not much American music that is really similar, there are several international bands that would come into my mind. Eg the Kaiser Chiefs or the latest Muse album, i think Starlight would have fitted perfectly onto Pasadena

I'd say the latest Billy Talent single (Surrender) also sounds remotely like barriers or motorology, though generally they play more uptempo punk stuff. You could also argue that they are not that successfull, but they are really big in Canada and Germany. And regarding Germany, several local bands come into my mind that are more or less similar to ozma and pretty successfull here, though you have probably never heard of any of them (wir sind helden, juli, sportfreunde stiller).
Of course, Ozma would need to publish the album and come touring europe, if they want to sell records here (*hinthinthint*
