Albums where artist/producer collaboration worked perfectly

[temes 19]

Many artists have albums that stand out as a career defining moments, and I think usually those albums are made with one or two main producers, and the collaboration between artist and producer(s) just works and the results are much better than expected. What's your favorites about these kind of artist/producer moments?

Here's few examples and my favorites:

Janet Jackson: The Velvet Rope (producer Jimmy Jam & Terry Lewis)

Gloria Estefan: Gloria! (producer Tony Moran)

Madonna: Ray Of Light (producer William Orbit)

Nelly Furtado: Loose (producer Timbaland)

Cher: Believe (producer Mark Taylor)

Alanis Morissette: Jagged Little Pill (producer Glen Ballard)

... I'd also like to include Whitney's My Love Is Your Love album to that list, but it was done with so many producers that it can't be called a Whitney/Rodney Jerkins moment.
