Sign is a brilliant non-team that assembled for Indications of Existence in 2000. Tag Mangold, who had written with Benny Mardones and Michael Bolton, also performed with American Tears and Contact. Mangold fulfilled Zebra’s basin of skill, Randy Jackson, in the first ’90s, and both strove to collaborate. Originally calling Brad Delp, the duo rather began dealing with Terry Brock (Strangeways, Kansas), who used Mangold on early Bolton slabs. Jackson drew on his Long Isle origins for Blue ?-yster Cult drummer Bob Rondinelli. Billy Greer also originated from the Kansas camp.
