That’s the piece Bells, from the album Winter Rose, recorded live at the Ruth Eckerd Hall in Clearwater, Florida, in the Fall of 2005. It is the trio plus string quartet. 
Here is a 2005 Diary post regarding that piece of music and here is another one from that particular concert in Clearwater.
It’s not a rumba or tangos. It’s not upbeat at all. It’s in a strange meter – 21/8. But it’s very nice music to hear while viewing the moon.
