I'm going to find this this weekend.

Here's the All Music review:

"Piazzolla was nearing the end of his distinguished career when he performed this concert in Switzerland in 1989; he divided it between playing classic material and debuting compositions. The first half was devoted to songs from the 1950s to the late '80s, while the second portion featured new material titled "Tango Nuevo, Nuevo." Each section was marked by swaying, hypnotic bandoneon solos with full lines, elegant melodies and romantic passages. This wasn't issued until a year after Piazzolla's death; it's a wonderful reminder of his greatness."
