British singer, pianist, songwriter, and performer Jamie Cullum can remind you a little of Harry Connick Jr., a little of early Billy Joel, a little of Elton John, even a little of Sinatra, and, ultimately, a lot of just himself. Cullum indeed draws from panoply of sources, but he’s been able to synthesize the best from each and transform it all into a personal style. Call it cabaret with a contemporary singer-songwriter edge. Mixing a handful of his own highly effective originals with a clever grab bag of well-loved standards and disparate rock tunes (Hendrix’s “Wind Cries Mary,” Jeff Buckley’s “Lover You Should Have Come Over,” and Radiohead’s “High and Dry”), Cullum somehow brings it all together effortlessly, betraying not a hint of self-consciousness. His all-embracing taste and blatant enthusiasm for a great song -- no matter its vintage -- combined with a true flair for singing and playing, mark this precocious “twenty-something” as a mature performer. It’s obvious we’ll be hearing lots more from this talented newcomer to our shores.
