question: What is the last name of the artist who put together a hip hop supergroup?
context: Sixteen days after his death, Wallace's double-disc second album was released as planned with the shortened title of Life After Death and hit No. 1 on the Billboard 200 charts, after making a premature appearance at No. 176 due to street-date violations. The record album featured a much wider range of guests and producers than its predecessor. It gained strong reviews and in 2000 was certified Diamond, the highest RIAA certification awarded to a solo hip hop album.
  Its lead single, "Hypnotize", was the last music video recording in which Wallace would participate. His biggest chart success was with its follow-up "Mo Money Mo Problems", featuring Sean Combs (under the rap alias "Puff Daddy") and Mase. Both singles reached No. 1 in the Hot 100, making Wallace the first artist to achieve this feat posthumously. The third single, "Sky's The Limit", featuring the band 112, was noted for its use of children in the music video, directed by Spike Jonze, who were used to portray Wallace and his contemporaries, including Combs, Lil' Kim, and Busta Rhymes. Wallace was named Artist of the Year and "Hypnotize" Single of the Year by Spin magazine in December 1997.In mid-1997, Combs released his debut album, No Way Out, which featured Wallace on five songs, notably on the third single "Victory". The most prominent single from the record album was "I'll Be Missing You", featuring Combs, Faith Evans and 112, which was dedicated to Wallace's memory. At the 1998 Grammy Awards, Life After Death and its first two singles received nominations in the rap category. The album award was won by Combs's No Way Out and "I'll Be Missing You" won the award in the category of Best Rap Performance By A Duo Or Group in which "Mo Money Mo Problems" was nominated.In 1996, Wallace started putting together a hip hop supergroup, the Commission, which consisted himself, Jay-Z, Lil' Cease, Combs, and Charli Baltimore. The Commission was mentioned by Wallace in the lyrics of "What's Beef" on Life After Death and "Victory" from No Way Out, but a Commission album was never completed. A track on Duets: The Final Chapter, "Whatchu Want (The Commission)", featuring Jay-Z, was based on the group.
