Kamille
As one half of the UK neo-soul group Floetry, Liverpudlian Marsha Ambrosius wowed fans with her smooth soulful vocals and her ability to lyrically capture the complexities of love, lust and loss. During her six years with bandmate Natalie Stewart, Ambrosius co-wrote their multi-Grammy-nominated debut album Floetic and collaborated with Michael Jackson on his last studio album Invincible, co-writing and providing backing vocals for his sensual R&B ballad Butterflies.
Since going solo, Ambrosius has written for Angie Stone, Alicia Keys and Solange; released three studio albums and received three more Grammy nominations - two of which were for the haunting single Far Away which details her real-life experience of losing a friend to suicide.
With 11 platinum singles, five UK number ones and over four billion streams to her name, former city stockbroker Camille 'Kamille' Purcell could be considered a songwriting unicorn.
As well as working with UK chart-toppers like Jess Glynne and Dua Lipa, the multi-award-winning songwriter is also the resident writer for pop starlets Little Mix. She's written 22 of their tracks so far - including the ultimate boy bye anthem Shout Out to my Ex-helping cement the group's position as leaders of the Girl Power 2.0 movement.
The secret to Kamille's success? Empathy. 'It's often us moaning about exes...just venting. That's my typical relationship with an artist, and it usually leads to a really good song,' she said in a recent interview.
The Leeds-based, singer-songwriter burst into the UK mainstream in 2006 after her distinctive bluesy vocals and songwriting talent saw her top the BBC's Sounds of list.
The accolade came off the back of Rae's first single Like a Star, a floaty acoustic ballad based on one of Rae's old flames. Her debut self-titled album proved equally as popular, topping the UK albums chart - making Rae the fourth British woman to do so - and earning Rae four Grammy nominations.
Following her husband's suicide in 2008, Rae took a short break from music before releasing her second album, The Sea. She has since said that writing the album helped her deal with her emotions at the time. However, her lyrics aren't necessarily 100 percent autobiographical. 'None of [my songs] are pages torn from a diary, which is what people think. It's art. It's made up, she recently said.
