kid on the block as far as baroque music is concerned, and his disc of Vivaldi arias capitalises on his growing reputation as both a vocal star and something of a sex symbol. The programme alternates macho coloratura numbers with suggestive nocturnes, many of them about the pleasures of erotic dreams and fantasies - though the title, "Heroes", is a bit of a blind, since some of the music was written for female characters. 　　Not everyone will like Jaroussky's voice: though appealing, he lacks the power of Andreas Scholl or the sensuous immediacy of David Daniels, while the sound has a tendency to harden at extreme ends of his range. His technique, however, is often staggering, and his breath-control in such languid numbers as the big aria from L'Olimpiade will leave you open-mouthed. There's some exquisite playing from the Ensemble Matheus under Jean-Christophe Spinosi, too. 　　Tim Ashley 　　Friday 12 January 2007 18.58 EST
