Her contemporary compositions are inspired by the majestic Welsh landscape that surrounds her. In 2013 the MATA festival for young composers, co-founded by Philip Glass, commissioned her to write a new work, which premiered in Brooklyn, NYC. The work is called 'Killing Time' and Tinnemans uses prepared knitting needles as part of the performing ensemble. Knitting stitches with these needles trigger the mercurial sounds of nature and wildlife she recorded and composed in her computer. The title is a wink to the craft of knitting, because it's more to do with the timelessness of the Pwll Deri coastal landscape. Jobina got approached by Vogue Knitting NYC and will stage this Pembrokeshire piece at their Live Event gala dinner in January of next year.
