In the Archiocese of Maringá, Brazil. The novel way of the entrance of the Gospel is quite interesting (1 minute into the video).
Contacted by a concerned Catholic by e-mail, the Archbishop of Maringá responded thus:
The pre-party masses are the mass of the Roman Ritual [sic] which all of us Roman Apostolic Catholics celebrate. It is just celebrated with certain symbols, dances, for young people... [sic]No one needs to be scandalized by this... [sic]God bless you!!Abp. Anuar Battisti
