Argentina's Los Natas (featuring guitarist Sergio Chotsourian)
debuted as a Kyuss clone on Delmar (1996),
but they adopted a more psychedelic stance for Ciudad de Brahman (1999).
They were back to some powerful rock'n'roll on Corsario Negro (2002),
containing the eight-minute Corsario Negro.
Even though this third album increased the "heaviness" of their sound,
they remained derivative of the classics of stoner-rock.
Then they moved to the other extreme with the
dilated acid-rock and prog-rock of Toba-Trance (Ektro, 2002),
containing just three lengthy suites:
the 21-minute La Tierra Delfin, that emits echoes of
early King Crimson,
Mike Oldfield
and Ennio Morricone
's spaghetti-western soundtracks before mutating into a vibrant space-rock jam for the second half;
the rather bland 14-minute Que Rico;
and
the suspenseful and drum-less 16-minute noise jam Die Possime.
Toba-Trance II (2003) added six pieces, notably
the 15-minute Traicion En El Arrocero and the lively eleven-minute
Jethro Tull-esque
Humo De Marihuana.
They then returned to stoner-rock for El Hombre Montana (2006).
Effective, but hardly original.
El Nuevo Orden De La Libertad (Nasoni, 2009 - Small Stone, 2009) was
a bit confused but featured the instrumental David Y Goliath.
Ararat, the solo project of Los Natas guitarist's Sergio Chotsourian,
continued the mission of Toba-Trance on
Musica De La Resistencia (MeteorCity, 2009), including the
14-minute Gitanoss and the
12-minute Magia Negra.
