高いチケットですね。どのくらいの密度の違いかわかりませんが、アメリカデトロイト市ではLabor Day ウィークエンドには無料のJazzFestがあるようです。http://www.patmetheny.com/news/full_display.cfm?id=102
かなり前から予告がありましたが"The Detroit Jazz Festival, the world’s largest free jazz festival, announced today that guitarist/composer Pat Metheny will be its 2015 Artist-in-Residence. Metheny is the latest in a long line of jazz greats to take the mantle of the prestigious Detroit Jazz Festival Artist-In-Residence Program, which will include different music incarnations at this year’s festival, as well as education and mentorship activities throughout the year. The 2015 Artist-In-Residence Program is sponsored by Absopure Water Company.
