Salsa, bossa nova, merengue, marimba -- Central and South America is a region of music, movement and irrepressible laughter. High up in the Andes, the low tone of Peruvian pipes envelopes the magnificent Inca fortress of Machu Picchu. Down by the sea, the cheeky residents of Brazil's Rio de Janeiro samba late into the night. The tango is more the taste in sophisticated Argentina, even on the plains of the Pampa. In Chile, home to both beautiful lakes and Atacama, the oldest and driest desert on earth, the locals dance a mean merengue. And in the strange and wonderful Galapagos Islands, living testament to the work of Charles Darwin, the lapping of the sea makes a music all of its own. Join in the fiesta that is Central and South America.
