Keeping in mind that Silver City collects most, but not all of the highlights of the period it covers and is probably the best choice for the "casual" fan of Rollins' 70s and beyond work (and I know a fair number of people for whom the issue of not liking this later work is simply a matter of them not liking Sonny's tone, or not likeing electric bass, or not liking any number of things that have nothing to do with the actual quality of the music itself other than personal taste as to style and such), here's the Milestone albums I keep coming back to and finding new dicoveries and enjoyments . They also contain material is not included in in the Silver City box that I would have included if I was compiling such a set.
Next Album

This Is What I Do
Then there's a few others, like Easy Living, Don't Stop The Carnival, Love At Frist Sight, No Problem, Sunny Days, Starry Nights, & Dancing In The Dark that have either one killer track on them and everything else just falls flat, or else the entire album misses the mark by just this much. Those are the ones that are really frustrating, the ones that tease you into thinking that if you can just figure out the proper perspective that you can get all the way into them, but that perspective never comes (or hasn't yet. By this time, though, if it hasn't happened...).
Also, all of these albums have at least one dog track, and it's usually one where the sidemen are featured at length. There's really no flat-out bad players on them, but when you're in the middle of an album where Sonny is playing quite nicely and for one cut, he just sort of steps aside, it not only drops the level of interest down, but it reinforces the point that Sonny Rollins, even if "studio mode", projects a quality and complexity of personality that is unique. As fine a player as Tommy Flanagan was, to use a "name" example, when, on some of these latter albums, Rollins stops and he begins, there's a noticeable shift (downwards, I think) in the "aura" factor. And that's Tommy Flanagan...
Anyway, that's my opinion. This is a matter that will never be settled, since it is based on, as should be obvious by the previous comments in this and similar other threads, each individual's perception of "who" and "what" Sonny Rollins "should" be, and to what degree he's delivering those particular goods. But consider this - there is no other player, dead or alive, who could play like Sonny Rollins plays today, in terms of technical specifics and also of projection/quality of personality. The guy's tone alone (and the absolutely huge sound with which he delivers it) is more complex than most people's entire musical makeup. Like, love, loathe, or remain indifferent to his work (live and/or studio) of the last 30+ years, I think that that must be acknowledged
