Oliver began collaborating with Indian singer-songwriter / Moushumi Bhowmik in 2002. Moushumi is famous for her classic songs Ami Shunechi Shedin and Jessore Road, and was also the music director of the the 2002 Cannes award-winning film Matir Moina (Tareque Masud, Bangladesh 2002). They played their first gigs as a duo in London and in 2005 they formed a band, Parapar, which toured West Bengal and Bangladesh. In 2007, a documentary, Bridging My Home, filmed in London and Kolkata by film maker Debanjan Bandyopadhyay, was released, focussing on Parapar's creative process. Their work together has also included theatre commissions, such as Walking To The Sun, (Prithvi Theatre, Mumbai 2010)
Parapar disbanded in 2010 and, after a short hiatus, Bhowmik and Weeks began playing together again as a duo. In 2016, alongside Satyaki Banerjee and Sukanta Majumdar, they recorded Moushumi’s first album in 16 years, Songs from 26H. The video for their re-working of Rabindranath Tagore’s Jibon Jokhon Shkaye Jay (above) was made by Indian photographer Ronny Sen and led to Oliver scoring Ronny’s first feature film, Cat Sticks (Slamdance 2019), to which Moushumi contributed a song for the closing titles.
“The result was not 'fusion' in the popular (and usually banal) sense of the word for authentic music is always already 'fused'… there is something intense and actual about the human sound of stringed instruments that matches the intellectually complex, often heart-breaking inwardness of Moushumis singing.” Aveek Sen, The Telegraph, Kolkata, 6 May 2005
