Estival Jazz, Lugano, Switzerland. Since 1977, Estival is a summer jazz festival in Switzerland, Lugano. Estival offers a thrilling and particularly surprising line-up that explores the rich world of contemporary music whilst promoting the understanding of different cultures, tolerance, and co-existence. McCoy Tynerâs first main exposure came with Benny Golson, being the first pianist in Golsonâs and Art Farmerâs Jazztet. Heâs also known for his work with the John Coltrane Quartet. Tynerâs style is easily comparable to Coltraneâs maximalist style of saxophone. Though a member of Coltraneâs group, he was never overshadowed by the saxophonist, but complemented and even inspired Coltraneâs open-minded approach. McCoy Tyner is considered one of the most influential jazz pianists of the 20th century, an honour he earned both with Coltrane and in his years of performing following Coltraneâs death.
