Performing bands included
The Byrds,
T. Rex,
Santana,
Jefferson Airplane, and the headlining
Pink Floyd. Approximately 100,000 attended. Festival posters show that the festival was billed in Dutch as
Pop Paradijs and 'Holland Pop Festival 70', and that the main investor was
Coca-Cola. In both English and Dutch, the festival is also known by the English name
Stamping Ground, and is often billed as the European answer to
Woodstock. It took place approximately one year after Woodstock, and two months before the third 1970
Isle of Wight Festival (the first two being held in 1968 and 1969). CountryJoeMcDonaldKralingen1970.jpg|Country Joe McDonald Optreden op Holland Popfestival in het Kralingse bos, 1970 - 02.jpg|Mungo Jerry & Ray Dorset StonetheCrowsKralingen1970.jpg|Stone the Crows TheFlockKralingen1970.jpg|

marijuana. The many present undercover cops did not arrest any of the users or small traders: it became clear that there were just too many, and all of them peaceful. In 1971, a documentary about the festival appeared, titled
Stamping Ground, created by
Hansjürgen Pohland aka Jason Pohland and
George Sluizer. The film was made for an international audience and is also known under the titles
Love and Music, and in Germany
Rock Fieber. Also, several books and exhibitions have been dedicated to the event. A triple lp-boxset was released in 2010. The Dutch Festival 1970 (Kralingen) was organized by Foundation "Holland Pop Festival" (Piet van Daal, Georges Knap, Toos v.d.Sterre, Berry Visser) On 21 September 2013, a memorial has been unveiled in the
Kralingse Bos area, to commemorate the first multi-day open air popfestival on the European continent.
