After playing a series of acoustic shows in the early 1990s, they were picked up by Columbia Records. In 1992 they released "Grave Dancers Union", which became their most popular album. On January 20, 1993, the group performed at the first inauguration of United States President Bill Clinton. Later that year, the band performed "Sexual Healing" for the AIDS benefit album "No Alternative", produced by the Red Hot Organization. The band added keyboard player Joey Huffman in the summer of 1993. He toured with the band until joining Matchbox Twenty in 1998. Huffman played on the albums "Let Your Dim Light Shine", "", and "The Silver Lining". Soul Asylum won the 1994 Grammy Award for Best Rock Song for "Runaway Train". The music video for that song featured photographs and names of missing children, in the style of a public service announcement. At the end of the video, Pirner appeared and said, "If you've seen one of these kids, or you are one of them, please call this number", and then the telephone number of a missing children's help line was shown. For use outside the U.S., the video was edited to include photos and names of missing children from the area where the video would be shown. The video was instrumental in reuniting several children with their families.
