I'll kick of with some recordings of my favourite French baroque composer:
François Couperin.
For me his compositions for the harpsichord are marvelous. Goes right beside Bach and Scarlatti.
What I like about these works is their idiosyncratic nature and dreamy, otherworldly character. At least that is what I hear!

I love my set of complete works by harpsichord giant Christophe Rousset to bits. Rousset is highly idiomatic in this, with a true instinct for Couperin's "poetry" He plays a superb, very sonorous and lush sounding harpsichord.
A cheap 2CD set with "highlights" is available, as is the stupendous "L'Apothéose de Lulli" for two harpsichords, played by Rousset and William Christie - extreme virtuosity and excitement!

Another favourite is the already mentioned
Leçons de Ténèbres. Very delicately played, perfect blending of the orchestra with the voices of Véronique Gens and Sandrine Piau! A dream cast.
Major vocal baroque works, which luckely enjoy an increasing number of recordings.

Couperin's organ masses are perhaps a bit of an acquired taste - fascinating and full of character!
Especially when played on authentic, really adventurous sounding organs as here.
