While Bossa Nova's heydey was in the late fifties and early sixties, this sound (heralded by Antonio Carlos Jobim, Stan Getz, and many more) has outlived its short burst of initial, high public popularity - as was most notably achieved through the chart-topping single "The Girl from Ipanema." In some ways a fusion of samba and jazz, bossa is a smooth, slinky form of music that grooves but often requires a great deal of technical skill. One musicain described it as "difficult music that sounds easy."
