I'll have a listen. Unbelievably, I've never listened to the Burrito boys. Thanks for posting.
As for the Everly's, Phil & Don were... sublime. Probably the greatest harmonies ever, and I am including John & Paul in my assessment
Regarding the Burritos, it's understandable you haven't listened to them. The "classic" lineup with Gram Parsons was here and gone practically in the blink of an eye. They lasted for two albums and that was it.
Regarding the Everly Brothers, I absolutely agree with you. Both were top-notch singers, and to top that off they had that "brother telepathy" going on that gave them that extra element. John and Paul were
heavily influenced by the Everly Brothers, and I guarantee you that they would both agree with us wholeheartedly. A quick little side note: The Everlys' golden era was way before my time. I listen to lots of music at work, and many of my co-workers are older people who can't believe I listen to the Everlys. I just tell 'em that it all boils down to cool parents and good taste!
