LD+3 is an album by American jazz saxophonist Lou Donaldson with the Three Sounds—consisting of rhythm section Gene Harris, Andrew Simpkins, and Bill Dowdy—recorded on February 18, 1959, and released on Blue Note later that year.

[2] The AllMusic review by Stephen Thomas Erlewine states, "Donaldson is at a fiery peak, spinning out Bird-influenced licks that nevertheless illustrate that he's developed a more rounded, individual style of his own.

The Three Sounds are equally as impressive, working bop rhythms with a dexterity that their first albums only hinted at.

That high standard is maintained throughout the album, one of the finest in either of their catalogs.

Albums like this and Blues Walk established Donaldson's reputation as a first-rate alto saxophonist, since he flaunts a full, robust tone, a fondness for melody, and nimble solos over the course of the record.
