Oh right- you’ve been on a Brazilian kick
Her self titled album from ‘68 is her best so I’d recommend starting there. The “Gal” album from ‘69 is also incredible but is pretty noisy and experimental at times. Next few albums “Legal”, “India” and “Cantar” are also very good and notably more accessible.
Yeah she was one of Brazil’s most popular musicians and is the first of the major tropicalia players to die.
