Singer-pianist Jamie Cullum, one of the most popular of the British musicians of the past 20 years, has the potential to perform practically anything.

Jazz is just a small part of what Cullum plays, but whenever he does, he displays the potential to be one of the best.

On this version of “What A Difference A Day Made” from 2006 with his trio, Cullum excels as both an expressive singer and as a jazz pianist; he should do this more often.
