Argentinian drummer Bolsa Gonzalez met the girls of CocoRosie during the recording sessions for their new album, 'Grey Oceans' in Miami. For that track Hopscotch, they needed a drummer and asked Bolsa Gonzalez. Says Bianca Cassidy: "We're not fond of rock drums at all, but we thought 'Why not invite him anyway?' So, we asked him to play on that song and we tried to explain to him what "jungle music" was, like drum and bass-processed drums sped up. That's not natural for anyone to play. It was hard for him and he was cussing, but he eventually nailed it."
