'Dusty... Definitely' from 1968 is considered one of her best albums. More a Pop production than its predecessors, on it she explored more and different genres than she had done before; the cover 'Take A Little Piece Of My Heart' and Motown-styled 'Ain't No Sun Since You've Been Gone' were produced by a young John Paul Jones (who had just gained fame with Led Zeppelin), and the album also features 'Who', written by Charles Aznavour, and the indelible 'Think It's Gonna Rain Today'', written by Randy Newman.
