Apart from being an outstanding pianist, organist, and composer, our Parisian friend
Benjamin Intartaglia is one of the world's foremost transcribers of piano rolls by performers such as Charley Straight, Max Kortlander, and J. Lawrence Cook. His talent is matched only by his generosity – many of his transcriptions are offered at no charge.
Admirers of Keith Jarrett will find many treasures on Simon Savary's transcription website. Monsieur Savary provides Jarrett transcriptions, by himself and others, that, as he puts it, "are not (and will probably never be) available in stores."
Do you have a recording or a lead sheet you want transcribed or arranged? The best transcribing gun-for-hire known to us is the pianist, conductor, composer, and pedant Seth Weinstein. Moreover, we hear he's one heck of a Scrabble player.
John Farrell, who passed away in 2007, was an accomplished stride pianist, and a master of transcription. Thanks to his daughter Alison, his marvelous sheet music, which includes some of the best Fats Waller transcriptions available anywhere, is still for sale, at very reasonable prices. His website includes free MIDI samples of his arrangements.
