Nice review from Improvijazzation nation : http://rotcodzzaj.com/42-2/improvijazzation-nation-issue-152/issue-152-reviews/
Jamie Dubberly & Orquesta Dharma – LA CLAVE DEL GUMBO: Totally cool Latin-oriented trombone-led jazz from California… the splendid opener, “Jazzy“, establishes the lively tone for the rest of the nine-song extravaganza. The 6:30 version of Marvin’s “Don’t You Worry ‘Bout A Thing” is among the best I’ve heard (yet) in 2015 & the vocal is totally killer! The groove on “West Side Strut” swings just as you might expect it to, & will have you up & dancin’ ’round th’ room in no time. It’s (most) strongly recommended that you listen to this with headphones for the first sitting (unless you have a house where you can set your amp to FULL TILT – then listen to it that way). The superb percussion on “Soul Provider” made it my personal favorite, as well as the “party spirit” the group projects. I give Jamie & his (rather extensive) crew a MOST HIGHLY RECOMMENDED, with an “EQ” (energy quotient) rating of 4.98 for this one.
