It’s not rare for jazz musicians to venture into the world of baroque, often with great success: so, asks Jos van Immerseel - why not the other way around? And so he decided to record... Gershwin. With the original instrumentation and arrangements, on period instruments! Gershwin's period, that is: not the period of sackbuts and cromornes. The piano used on Rhapsody in Blue was a 1906 Steinway; the piece was first orchestrated by Ferde Grofré in 1906 for a jazz band (Gershwin had dragged his feet and dawdled and the work was finally performed before the ink was dry: and even then, the piano part appears to have been almost completely improvised). Also present are the tranquil vision of an American in Paris as distilled by Immerseel; several songs by Claron McFarren, who is certainly not of that era, but whose voice cleaves closely to a recognisable North American inter-war style; while Gershwin's Magnum Opus, Porgy and Bess, is presented as an orchestral suite. There is no accounting for taste, and everyone will form their own view of this baroque-jazz interpretation of the tradition. But whatever your own personal preferences, this is an experience not to be missed.
