I say good fortune because ACSM is a short hop from the Louis Armstrong House Museum in Corona, and an even shorter hop from where the Louis Armstrong Archives, in their entirety, were tucked away at the time, behind a secure door off the front entrance of Queens College’s Rosenthal Library. (They’ve since been moved to the newly constructed Louis Armstrong Center, across the street from the Museum.) The Solo: PreludeI can’t remember if I discovered Armstrong’s 1925 “Alone at Last” solo through Ricky or somewhere else. Well, one thing is perfectly clear: A jazz solo can certainly change jazz, and Armstrong’s solos did that, as did his vocals. It is the sound of Louis Armstrong, the sound of America.
