Arrangement for Piano Solo. The arranger's notes tell us: 'Libertango stands for the freedom which I allow for my musicians. Their limits are defined solely by the extent of their own capabilities and not throughany exterior pressure, like Astor Piazzolla. Piazzolla wrote the Libert ango for his Octeto Nuevo de Buenos Aires which he formed after returning from Paris in 1954 'determined more than ever before to treat the tango as music.' An absolute music, based on the melodic, harmonic, and above all, the rhythmical qualities of the tango, frees it from the sociallydefined context of its origins at the beginning of this century'.
