We're trained as listeners to appreciate singers who project, who have voices that abound, that can break glass, that can match Pavarotti in operatic resonance. Virtuosos, most say, have lions' voices. Life and music are not always declamations, however. Sometimes a sigh steps over a shout. Such is the case with the following two songs off recent releases from the Yeah Yeah Yeahs and Laura Gibson. Both Karen O of the YYYs and songwriter Gibson suspend on a wispy cloud of vocal ether far above the grounded instruments. Enjoy their transcendence and enjoy the temperate temperatures.
