Remembering Toots

Mathias Heise pays tribute to his great harmonica idol Toots Thielemans. It is a musical experience varying from solo harmonica to quartet jazz with compositions that in one way or the other relate to Toots Thielemans – seasoned with anecdotes from Toots’ career. A musical sight seeing through swing, bebop, samba, bossa, and pop – and of course some of Toots’ greatest hits!


Heise/von Bülow Duo

Mathias Heise and guitarist extraordinaire Pelle von Bülow play standards as well as original compositions by Mathias Heise. The style is soul and jazz with one or two Danish classics thrown in.
