The band supported "Sweet Oblivion" with a year-long tour, during which tension developed among the members. After the tour was finished, the group took an extended hiatus. During that time, Lanegan recorded his second solo album, "Whiskey for the Holy Ghost", which was released in 1994. The following year, Lanegan was featured as a guest vocalist in the Barrett Martin (alongside with Layne Staley and Mike McCready) side project Mad Season. Lanegan co-wrote and sang on two songs. Mad Season would only release one album because of Staley's deteriorating health and the 1999 death of bassist John Baker Saunders.
