A native of Buenos Aires, Argentina, who now lives in New York City, Pablo Aslan has specialized in an acoustic-oriented blend of tango and post-bop jazz in the ’90s and 2000s. The acoustic bassist is not a tango purist any more than he is a jazz purist; although Aslan has been greatly influenced by the late bandoneon innovator Astor Piazzolla — a musical revolutionary who was as important to tango as alto saxophonist Charlie Parker was to jazz — he has also been affected by jazz greats who range from Oliver Nelson, Duke Ellington, and Charles Mingus to Gato Barbieri and Charlie Haden. Aslan isn’t known for what jazz musicians call “blowing dates” — that is, loose and informal sessions that emphasize blowing, jamming, and improvising. Rather, the Argentinean musician is coming from more of a bandleader/composer/arranger perspective, which is something Aslan has in common with Nelson, Ellington, and Mingus. One hears a lot of Mingus‘ abstraction in Aslan‘s tango/post-bop work.
