4 is a live album by composer and saxophonist Anthony Braxton with a ninetet, recorded at the Yoshi's in 1997 and released on the Leo label in 2007 as a double CD.

[1][2][3] The Allmusic review by arwulf arwulf stated "When in August 1997 the Anthony Braxton Ninetet performed live at Yoshi's in Oakland, California, the methodology he called Ghost Trance Music still contained elements of its "first species" stage, in which the primary rhythmic pulse was generated in honor of the First Nation Native American drum ritual tradition.

Although by this time Braxton's Ghost Trance Music had been evolving for little more than two years, greater systematic variability is evident throughout the intricate and complex "Composition N. 213" and "Composition N. 214," which may reflect GTM's other primal influence, the Indonesian Shadow Puppet Theater tradition.

This is the Braxton Ninetet's fourth and final recording made during that five-day engagement at Yoshi's in 1997".

The scored music is entirely consistent with those preceding releases; highly structured and rhythmically tight, it gets into a groove and then stays there for a long time.
