A number of things are happening in the splintered Pell Mell camp. The project that Bob mentioned to me last year is slowly working on an LP worth of tracks. It is called Grimspex and is a collaboration with Gary Waleik from Big Dipper. Take a listen to the tracks on the MySpace page.
Greg Freeman has a project called Checksum with Jeff Palmer that is worth checking out. They have a new album called Grey Ghost that came out on Box Kite Records in 2006.
Bob also said that Dave Spalding has been playing around New York City lately.
