Not surprising, since it was produced by John Medeski from Medeski, Martin and Wood.  If you’re not familiar with the jam band thing, in essence it involves long and complicated instrumental solos that border on jazz.  No problem for the Campbell Brothers, according to producer Medeski who wrote in the CD notes that they are “some of the most technically advanced players I’ve ever had the pleasure of working with...”  Some jam band stuff becomes almost too technical, but with the Campbell Brothers’ base in gospel, that doesn’t happen much on this CD.  3 ¾ bottle caps out of a possible 4.
