Gramophone http://www.gramophone.co.uk/cdreviews.asp is always a good resource to mine for recommendations. Here are three reviewed in that source that I'd consider:
Emanuel Ax pf
Orchestra of the Age of Enlightenment/Charles Mackerras
Sony Classical CD SK60771 (64 minutes : DDD)
"This companion issue to Emanuel Axs outstanding disc of the Second Concerto (6/98) and other concertante pieces similarly offers period performances unlikely to be outshone for their imagination and poetry. Ax disarms criticism over the idea of period performance by choosing an Erard piano of 1851, which produces warm, full tone without any restriction on agility, thanks to the light action. Only the clattery quality in the topmost register betrays the age of the instrument, and the transparency of textures is a delight, with the writing for left hand articulated by Ax with phenomenal clarity. Mackerras heightens the drama of these readings by encouraging the OAE to produce the widest range of dynamics, equally defying the idea of period performance as lacking in weight."
Martha Argerich pf
Montreal Symphony Orchestra/Charles Dutoit
EMI CD 556798-2 (69 minutes : DDD)
"Martha Argerichs first commercially released recordings of the Chopin concertos were for DG; No. 1 with the London Symphony Orchestra under Abbado in 1968, No. 2 with the National Symphony Orchestra under Rostropovich in 1978. Today, she revisits both concertos with the Montreal Symphony Orchestra under Charles Dutoit and offers an act of recreative daring, of an alternating reverie and passion that flashes fire with a thousand different lights. Indeed, her earlier performances (see mingly non pareil at the time) are infinitely less witty, personal and eruptive, less inclined to explore, albeit with the most spontaneous caprice and insouciance, so many new facets, angles and possibilities. Now, everything is accomplished without a care for studios and microphones and with a degree of involvement that suggests an increase rather than a diminution of her love for these works."
Garrick Ohlsson pf
Polish National Symphony Orchestra/Jerzy Maksymiuk
Unesco Classics New CD DCL70630-2 ( ADD)
"In Garrick Ohlssons recordings of the two Chopin piano concertos the CD transfer of the analogue stereo master seems to retain all the best elements of the mid-70s sound, combining spaciousness with good focus and a natural perspective. Ohlssons performances are most impressive poetic, with finely nuanced but unexaggerated rubato, an often sparkling bravura and never rambling in passagework. Maksymiuks accompaniments are fully supportive and have plenty of character. Most enjoyable."
