To cantoresque, There’s a cd of a concert that Muller gave in Manchester with his sons where he sins the braisa of Rabi Yishmoel beutifully, He also does a great job with Gonchoff Shir Shel Haleviem (wich he completley redid.
Incidently he has a son in Manchester who I’ve heard could be better then him but I don’t know of any recordings he’s done.
