Aaron Freeman, better known by his stage name Gene Ween, is an American singer, guitarist and a founding member of the experimental alternative rock group Ween. Freeman, along with childhood friend Mickey Melchiondo, started the group in the mid-1980s. Ween would expand to five members and perform together until May 2012 when Freeman abruptly quit the band due to his want to move forward with a solo career, as well as his desire to remain sober. Over the next few years, Freeman would briefly abandon the Gene Ween name and lead a new five-piece band called Freeman. Shortly after reviving the Gene Ween name for a series of Billy Joel tribute performances, Ween reunited in February 2016 for three concerts in Broomfield, Colorado. The band has continued to perform and tour since.

Michael Melchiondo Jr., better known by his stage name Dean Ween, is an American guitarist, singer and a founding member of the alternative rock group Ween. He is currently active in the groups Ween, Moistboyz and The Dean Ween Group.
