The soaring highs and deep lows of the Rhythm and Vines festival are revealed in a "warts and all" documentary being released by the New Zealand Herald tomorrow.

The Road to Rhythm is a four-part series chronicling the 15-year history of the popular music event near Gisborne.

It follows the festival's roller-coaster ride - including some of the big-name acts it's featured, ultra-ambitious plans from festival bosses, huge financial losses which left its future in doubt and what now appears to be a positive future for the music celebration.

Rhythm and Vines began as a dance party for University of Otago students and has since become New Zealand's premiere New Year's festival.

Among aspects covered in the doco is a strained relationship between festival co-directors Hamish Pinkham and Andrew Witters.

Pinkham described the series as "certainly warts and all".

The future now is looking a lot more secure for the festival, recently going into partnership with Live Nation.

In April, Live Nation announced it had taken a controlling interest.

"Over the course of 15 years, Rhythm and Vines has curated a wonderful line-up of both domestic and international talent in one of the most beautiful parts of our country.

"It has become a household name [nationwide] and we're excited to be adding the festival to the Live Nation portfolio and welcoming its experienced team to the company," said Live Nation New Zealand chairman Stuart Clumpas.
