19 Standards (Quartet) 2003 is a live album 4CD box set by American composer and saxophonist Anthony Braxton recorded in Europe in 2003 and released on the Leo label in 2010.

The creative small group dynamic developed by Braxton over several decades is very much in evidence as he interacts with bassist Andy Eulau, percussionist Kevin Norton, and guitarist Kevin O'Neil.

Braxton's choices are astute and varied enough to make this an exceptionally satisfying effort".

[3] All About Jazz reviewer Glenn Astarita noted "they inject a modernist edge into the roads previously traveled.

With sterling musicianship, the quartet expressively melds sheer firepower with elegance, and a persuasive mode of execution, which seeds a refreshing ambiance into these time-honored standards".
