The Red Hot Chili Peppers concert at Slane Castle in Ireland in 2003 is one of the most impressive live performances of their career, with over 80,000 people gathered in the castle gardens under an Irish sky that seemed designed for the occasion.
The show captured the band at their best commercial and artistic moment, presenting a setlist covering all of By the Way along with classics from Blood Sugar Sex Magik and Californication, in a performance of over ninety minutes that became a reference for outdoor rock.
Slane Castle 2003 is today considered one of the best recorded concerts in the history of alternative rock: the stage energy, the crowd response and the musical quality combined to create an unrepeatable moment.
