They were subsequently signed to Universal Music's Island label. Now composing and writing their own songs, Cimorelli is made up of five sisters: Christina, Katherine, Lisa, Amy, and Lauren; their older brother, Mike Jr., was a member of the group from 2007 to 2008, while youngest sister Dani was a member from 2010 to 2020. The group's music is mostly made up of a cappella singing with occasional instruments.
