Nelson is a sibling act founded by Matthew and Gunnar Nelson, the twin sons of 1950s teen idol Rick Nelson. During the early '80s, the brothers joined a heavy metal band called Strange Agents. By the end of the decade, however, the group's name had changed to Nelson, as the twins were the only remaining members. With Matthew on bass, Gunnar on guitar, and a handful of music vets onboard (including guitarist Brett Garsed and former Vinnie Vincent Invasion drummer Bobby Rock), Nelson made its debut in 1990 with the release of After the Rain. Filled with polished, radio-friendly pop-metal, the album was a major hit in America, where it sold over a million copies and charted a number one single with "(Can't Live Without Your) Love and Affection." Three additional singles cracked the Top 40.
