Slank drummer Bimbim said on Friday that the concert aimed to involve Indonesian musicians in a celebration of democracy. He emphasized that the participation of the musicians was voluntary.

“It’s our conscience that encourages us, not money,” Bimbim said.

Guitarist Ridho said the concert would also voice appeals to attendees to stand up for a better Jakarta.

“[Ahok-Djarot] are brave and honest in handling the complex bureaucracy. That’s the similarity between Ahok and Slank,” Ridho said.

Noted musicians Tompi, Once, Sandhy Sondoro, Kikan, Krisdayanti, Dira Sugandi, Shanty, Gita Gutawa, Project Pop, Happy Salma and Iwa K. are also scheduled to perform at the concert, which will take place at the Ex-Driving Range Senayan in Central Jakarta.

Ahok-Djarot’s campaign team spokesman, Ansy Lema, said Slank would also release a campaign song for Ahok entitled “Gue 2” (I am two).

“Slank is renowned for their songs that bring an anticorruption and antidrug message,” Ansy said.

Slank has also been chosen as an anticorruption ambassador by the Corruption Eradication Commission's (KPK) and an antinarcotics ambassador by the National Narcotics Agency (BNN).

During the 2014 presidential race, Slank was also featured in the campaign of President Joko "Jokowi" Widodo and Vice President Jusuf Kalla. (bbs)
