Mackintosh was a Dutch singer, composer, actress and writer, born in Amsterdam, and the daughter of Surinamese singer Max Woiski, Jr. and granddaughter of musician Max Woiski, Sr. At seventeen she was talent scouted by the Dutch actor Jack Monkau and traded a formal education for a career in music.

Next she played key roles in the Dutch rock opera Ik, Jan Cremer and the high-profile musical Barnum.

In 1977, Mackintosh released her first jazz single, a cover version of the Rodgers and Hart classic "My Funny Valentine".

That same year the Beets Brothers released the first-ever Dutch jazz DVD, featuring Mackintosh and Hans Dulfer.

A close collaboration with saxophone player Wouter Kiers led to the release of the concept album Comes love in 2005.

The album coincidentally marked the start of her long-term collaboration with the Dutch saxophone player Clous van Mechelen.

In this version, extra care was taken in finding the right balance between voice and band to achieve the highest possible sound quality.

In these master classes Mackintosh used her experience to help aspiring singers further develop their voices, to use the stage to their advantage, and above all, to emote.
