Ultimate High is the debut album of Irish-born singer Carly Smithson, released under her maiden name Carly Hennessy in 2001 by MCA Records. It failed to find an audience despite getting good reviews and MCA Records spending over $2 million on the production and promotion of the album, and became a textbook example for the economics of today's music industry.The song "Just Missed the Train" was later covered by American Idol season 1 winner Kelly Clarkson in her debut album Thankful.
