After an extremely successful world tour and extensive airplay for their 3 videos on MTV, van den Berg co-wrote all of the music to the follow-up album "Slip of the Tongue". Injury prevented him from recording for the album, so Coverdale enlisted Steve Vai to record both lead and rhythm guitar. Van den Berg was sufficiently healed to play with the band, in a dual-guitar role alongside Vai, for the tour supporting the album. After Whitesnake was disbanded in 1990, he returned as part of other Whitesnake incarnations such as the 1994 "Whitesnake's Greatest Hits" reunion/tour. He once again co-wrote the songs for the 1997 album "Restless Heart" with Coverdale. This time, he played all of the guitars on this stripped-down, bluesy album, turning away from his well-known rock/metal neo-classical chops and towards his original main influence, Jimi Hendrix. He also collaborated with Coverdale on the Whitesnake unplugged acoustic album, "Starkers in Tokyo".
