In 2005, Serendipity were chosen as Cor Cymru 2005. This, together with their existing reputation has led to numerous future opportunities such as the opening night of the 2005 Faenol festival, and Bryn Terfel’s Christmas concerts in both the Wales Millennium Centre and the Royal Albert Hall.
2006 saw the choir performing in an Opera gala with Bryn Terfel, a performance with Catrin Finch's big band, and the release of their debut album titled Ad Majorem Dei Gloriam. The album consists of music of the English Cathedral tradition, German Romanticism, American contemporary choral music and their own tradition of Welsh Sacred music.
Additionally, the choir has recorded music for the film soundtrack Hawk and has performed with artists Katherine Jenkins, Juan Diego Florez, and José Carreras.
