for the Septeto del Sur, six brilliant Chilean musicians
The first tune is one titled "Suite Para Todos" (Suite for All) that begins with a slow milonga, then a rather martial sound (which you hear the ending of at the beginning of he video), then free improvisation leading back into the slow milonga form.

"Mercedes Sosa" a tune that I wrote 25 years ago to honor the great Argentinian singer Mercedes Sosa. After the head, we all take turns playing solos, each solo leading into a duet, another solo, another duet, etc. Then we return to the head.
The Septeto del Sur is:
Luis ToTo Alvarez (guitar), Bob Pa Tiño (Rodrigo Bobadilla - flute, quena, zapoña), Carlos Canales Sierra (charango, flutes), Manuel Estay (drums), Amanda Irarrazabal (double bass), Danka Villanueva Bono (violin), and yours truly on the pedal steel guitar.
