A Brazilian organist/composer who stumbled upon a gold mine in the 1960s, Walter Wanderley has been resurrected posthumously in the 1990s, a purveyor of lounge music for a young generation. Yet his sound on the organ, generated by a crisp, lightweight, staccato attack, can be mistaken for no one else's - and his choice of material showed much good taste, particularly when exploring his countrymen' s songs. Although his most popular records contained only a minimum of melodic jazz improvisation, he could stretch out when he wanted to.
