Vandenberg's 1982 debut LP did reasonable well, reaching #65 on the album charts, helped by the "Burning Heart" single, which reached #39. Note that Vandenberg's song is totally different from Survivor's "Burning Heart" (a #2 hit from 1985, from the from Rocky IV soundtrack).
A successful debut album, a hit single, and a melodic hard rock sound should have translated to further success, but Vandenberg's second and third albums did not do well, and the band broke up in 1986. The following year, Adrian Vandenberg joined Whitesnake, and remained with them through the remainder of the decade.
Adrian Vandenberg remains active in the industry as of this writing - and is also a painter.
