Blue Angel is the 15th studio album by English band Strawbs. It was the first Strawbs album in 12 years to contain new material and featured several different line-ups of musicians from past Strawbs eras. Welsh folk-singer Mary Hopkin featured on many tracks, continuing a working partnership established by Dave Cousins and Brian Willoughby on their album The Bridge, from which several of the tracks on this album are drawn.
The track "Blue Angel" is a rearrangement of the track which appears on Dave Cousins' first solo album Two Weeks Last Summer. "Lay Down" is a re-recorded version of the hit single from Bursting at the Seams. "Sealed With a Traitor's Kiss" is a rearrangement of a track which appears on 1978 studio album Deadlines. The bonus track is the original 1979 version - also released as a single - of a track which later appeared on the 1991 studio album Ringing Down the Years.
