That's All is an album by American singer Bobby Darin released in 1959 and arranged by Richard Wess. It was on the Billboard LP charts for 52 weeks and peaked at number seven. It also includes Darin's US #1 hit "Mack the Knife". Darin won Grammy Awards for Record of the Year and Best New Singer.
Music critic JT Griffith called That's All Darin's "most important record" in his Allmusic review, also writing it "broadened his appeal and secured his imortality [sic]... [It] might not be a new fan's first Darin purchase. However, it is an important release in the Rock and Roll Hall of Famer's career. This LP proves that not every rocker suffers the "sophomore slump."
