Overview:This limited-edition release features a landmark performance by German electronic band Tangerine Dream (marking its 40th anniversary in 2007) at Britain's Coventry Cathedral. The video blends edited footage from the 1975 show with music from the group's "Ricochet" album released that same year. The concert is notable in part because German aircraft bombed and partially destroyed the cathedral during the Coventry Blitz of World War II.
