The Jimmy Rushing vocal track on Ellington's Jazz Party always slays me! I like his other Columbia lps as well.
I found a bunch of radio broadcast lps from the bebop era, like the Dragon lp Bebop enters Sweden, with Dizzy Gillespie big band, Chubby Jackson group, James Moody; Charlie Parker's 1949 Carnegie Hall concert, and others. Also, Howard Rumsey's Lighthouse All Stars on Omega, which sounds real nice.
