Firefly

Firefly is the tenth studio album by English rock band Uriah Heep. It was released in March 1977 by Bronze Records in the UK and Warner Bros. Records in the US. It was their first album without lead vocalist and founding member David Byron, and the first of three albums with new singer John Lawton, formerly of Lucifer's Friend. Bassist Trevor Bolder, formerly of the Spiders from Mars, the backing band for David Bowie, made his Uriah Heep debut on this album. Barring a break of about 18 months in the early 1980s, he remained with the group until his death in 2013.

The first single from the album was "Wise Man".

The original vinyl album was a gatefold sleeve, with a cardboard lyric liner.

The album was remastered and reissued by Castle Communications in 1997 with four bonus tracks, and again in 2004 in an expanded deluxe edition.
