One of the many wonderful things about Cortez the Killer by Neil Young and Crazy Horse is that they just start with over 3 minutes of guitar solo. It’s also there in reduced form for the coda. If it’s this good then why not. So other songs (must have vocals) in which they decide to go with the solo first (if it’s flugelhorn or harp even better) and make the vocalist sit on their stool for a bit.
