The big question was, would The 5 Countertenors, a new Decca release, offer its five stars in stirring ensemble, in the manner of the legendary Three Tenors?
They don't; each is allotted two arias with the faultlessly stylish Armonia Atenea ensemble, under George Petrou.
The Baroque repertoire searches out the obscure, but punters will not be disappointed with an aria from Gluck's Demetrio, poignant and spirited by turns, delivered with thrilling coloratura by Valer Sabadus.
Other highlights include the smooth lyricism of Vince Yi singing Josef Myslivecek and Yuriy Mynenko in fine, florid form for Johann Christian Bach. Yet there are let-downs, one being the lack of tonal finesse from the usually reliable Max Emanuel Cencic.
Meanwhile, on Warner Classics, Philippe Jaroussky easily secures his status as the most enterprising of today's countertenors, with a new double album Green, bringing together settings of the poetry of Paul Verlaine.
How could one resist a project that has the personable Jaroussky confessing to secret passions and pleading, "Why should a countertenor not have the necessary sensitivity and vocal technique to perform French melodies?"
He does, in heaps, as he did in 2009's Opium album, exploring the same territory with pianist Jerome Ducros.
Even sceptics must swoon at this man's elegant phrasing and silken tone singing familiar settings by Faure, Hahn and Debussy -- his poised, almost skittish Mandoline being just one instance of his very special partnership with Ducros.
The 43 songs offer different composers interpreting the same Verlaine poems. While Benoit Duteurtre's eight-page booklet essay offers valuable guidance, there is an adventure to be had independently navigating four different takes on Il pleure dans mon coeur by Faure, Debussy, Florent Schmitt and Charles Koechlin.
Jaroussky coaxes estimable colleagues along into the studio, from contralto Nathalie Stutzmann, duetting in Massenet, to the hip Quatuor Ebene, equally at home with Bruce Springsteen as Shostakovich.
Their dozen collaborations include zesty numbers by chansonniers Leo Ferre and George Brassens, spreading the same joie de vivre as Anne Sofie von Otter's Grammy-winning Douce France. Taste the final Brassens track and you'll want the whole set.
Verdict: French countertenor proves that a memorable album starts with a strong concept
