During their decade-long union, Jakarta-based GAC—siblings Gamaliél and Audrey Tapiheru as well as Cantika Abigail—became the leading co-ed vocal group in Indonesia, thanks to their funky, R&B-tinged pop. The three-piece rose to prominence in the late 2000s by posting covers of pop hits by Lady Gaga, Jason Mraz and others. A self-titled debut arrived in 2012; while 2015’s Stronger featured a collaboration with Alisha Attic’s Karen Poole and hits like “Happy” and “How Worth”.
