The family of late rock musician Jimi Hendrix has threatened to take legal action over a $15m (£7.9m) sale of some of his best-known songs.
Hendrix is remembered for his performance at the 1969 Woodstock festival
A company owned by Hendrix's family has said it will prove it owns the title and rights to hits including Purple Haze and Voodoo Chile.
The songs were auctioned on Thursday as part of the estate of Hendrix manager Michael Jeffery, who died in 1973.
The rock guitarist died in London three years earlier at the age of 27.
A spokesman for the Seattle-based Experience Hendrix company said: "Whoever bought this bought themselves the right to be a litigant.
"It will be contested instantly," added Bob Merlis.
The company claimed that it owns all rights to the music and recordings of the musician.
The Chicago-based auction house which conducted the telephone sale in New York declined to comment.
Hendrix continues to sell around 600,000 albums a year worldwide.
