Check out this deep groove/solo from Ernst Reijseger:
I first heard of Ernst Reijseger from the soundtrack to ‘Cave of Forgotten Dreams’. I just remember these scenes in the film that sounded improvised, yet oddly baroque in style. Were these modern baroque improvisations? It ends up that the cellist was a former student of Anner Bylsma. According to an interview, Bylsma encouraged him to break off from a career path of ‘classical’ music and told him to do his own thing. I’m really glad he did!
