The Austin Piazzolla Quintet, which plays Gig Performance Space (1808 Second St.) at 7:30 p.m. on Saturday, April 18, pays tribute to the great Argentine musician, Astor Piazzolla, who was born in 1921 and died in 1992. He studied the bandoneón from the age of eight and within a decade was performing with Aníbal Troilo’s renowned orchestra. He continued his studies with Bartók and Stravinsky. During his career he advanced the tango vocabulary, creating the “tango song”; composed symphonic works; and incorporated electric instruments into the music of his Conjunto Electronico octet. The members of the Texas-based group are founder and violinist James Anderson, pianist Jonathan Geer, cellist Tony Rogers, bassist Pat Harris, and Mike Maddux on accordion and bandoneón. They specialize in pithy arrangements of Piazzolla’s original songs and their own compositions. Improvisation is a strong part of the group’s performance. “Much like jazz, if you only play what’s on the page, it lacks the passion, personal emotion, and sense of freedom which it absolutely needs,” Anderson says. Admission to the concert is $20; visit www.gigsantafe.com.
