Baker earned much attention and critical praise through the 1950s, particularly for albums featuring his vocals (such as "Chet Baker Sings"). Jazz historian David Gelly described the promise of Baker's early career as "James Dean, Sinatra, and Bix, rolled into one." In 1952, Baker joined the Gerry Mulligan Quartet, which was an instant phenomenon. He became an icon of the West Coast "cool school" of jazz, helped by his good looks and singing talent. "Chet Is Back!" was recorded in Rome, Italy in 1962 at RCA's studios. The album features an original composition, "Ballata in forma di blues" (A Ballad in Blues Style), by Amedeo Tommasi. Ballads are also featured such as the standards "Over The Rainbow" and "These Foolish Things". This recording has been mastered by the K2 HD format of 24-bit 100kHz, which creates an unbelievable sound surpassing other formats. This K2 HD Mastering CD will play on all CD players.
