This Thursday an arts festival begins in the Moravian town of Boskovice. It will include jazz and rock concerts, including many household names here in the Czech Republic - the unusual and highly imaginative singer and violinist Iva Bittova, jazzman Jiri Stivin, rock bands Psi vojaci and Uz jsme doma, and many others. One band - Kangaroo Moon - is coming from as far afield as Australia, and there will also be theatrical performances and exhibitions. But, as found out, this is no ordinary summer festival.
