Elvis Presley, starting from 1954, recorded in his entire career more than 400 songs, the discs being sold in over 260 million pieces. His first hit, Heartbrake Hotel became in 1956 the symbol of rock'n'roll music of the time and the non-conformism of younger generations. Other popular songs from that time were: Blue Suede Shoes, Hound Dogs, All Shook Up etc. His career took a break in the time of the military service. After he returned on the stage, a change has been noticed in his musical style. Elvis gave up on his lively style, for one more slow, composing a few ballads. Cu placere!
