Safe Trip Home is the warm, moving and wonderfully musical third album from Dido, the London-born singer-songwriter with the cracked-crystal voice. The first, you might remember, was No Angel, a record made when Dido was a part-time backing singer with a tiny budget and no label. When that record's heartfelt snap-shots of life were released in 1999, nobody, least of all Dido, expected the album to eventually become the planet's biggest seller of 2001.
