Recorded in 1959, this album quickly became a jazz classic.

From Wikipedia:

"David Warren Brubeck (born December 6, 1920 in Concord, California, better known as Dave Brubeck, is a U.S. jazz pianist. Often regarded as a genius in his field, he has written a number of jazz standards, including "In Your Own Sweet Way" and "The Duke". Brubeck's style ranges from refined to bombastic, reflecting his mother's attempts at classical training and his improvisational skills. Much of his music employs unusual time signatures.

His long-time musical partner, alto saxophonist Paul Desmond, wrote the Dave Brubeck Quartet's most famous piece, "Take Five", which is in 5/4 time and has endured as a jazz classic. Brubeck experimented with time signatures through much of his career, recording "Pick Up Sticks" in 6/4, "Unsquare Dance" in 7/8, and "Blue Rondo à la Turk" in 9/8. He also provided music for TV animated miniseries "This Is America, Charlie Brown"."

An Online Reviewer:

"Time Out" is by far my favorite jazz album of all time. I never get tired of hearing it. It would definitely make my list of desert island discs. I also dig the painting which serves as the album cover. The superb pianist Dave Brubeck is the nominal leader of the group, frantically kicking off the opening classic track "Blue Rondo A La Turk." Drummer Joe Morello amazingly keeps perfect time during all of the tempo shifts. He particularly shines on the appropriately named tune "Pick Up Sticks." Saxophonist Paul Desmond takes center stage on the most famous track of all, "Take Five." This song has rightfully taken its place among the greatest instrumentals of all time. Rounding out the quartet, Eugene Wright's bass deftly anchors the beat on the melodic "Kathy's Waltz." The song "Everybody's Jumpin'" would be right at home on an album of sophisticated swing music. I'm no jazz expert who can expound on exotic time signatures, but I know what I like. I love "Time Out" by the Dave Brubeck Quartet!"
