Expanding on the trio setting of NY tenor saxophonist Ivo Perelman's "Strings 3" album, the 4th of the planned 7 CDs adds pianist Matthew Shipp to create a quartet that, while somewhat conventional on the surface, in practice emphasizes a string-like approach in both the woodwind and brass components, Shipp's perspective adding a unique dimension to the collective improvisation.

The 3rd album of NY-based Brazilian tenor saxophonist Ivo Perelman's Strings series with Mat Maneri on viola adds trumpeter Nate Wooley, an unusual instrument for a string series, but in the adaptable creative intent of Wooley's playing the trumpet is found intertwining with the strings and Perelman's cello-like sax runs to create a remarkable complement in their collective voice.
