Very nice format - deserves some decent FM outlets in major and medium markets, in my opinion. I'm glad for the occasional "instrumental" number mixed into each hour - makes the vocals stand out and adds a nice touch. Perhaps some more mainstream and "crossover" jazz, like Wynton Marsalis, Dave Brubeck, Pat Metheney, etc. would fit, too, and provide a sort of bridge from the smooth jazz stations that are giving up on that format. If it fits sonically with the mood, I say play it! And daypart a slower tempo at night to make it sound really cool.
Is it airing anywhere on terrestrial radio yet?
