David Gilmour: S/T (1978)
Still, David Gilmour's first solo album is the one I probably enjoy most; yes, it's a bit bland, but does have a few highlights that at least warrant its inclusion in the broader Floyd discography (and, having been recorded shortly after Animals, has a few tunes that sound a bit like Animals leftovers). And while Waters' solo work is clearly more impactful on a lyrical level, this one has the benefit of Gilmour's reliably solid bluesy guitar work.
It actually starts off fairly strong. Opening instrumental "Mihalis" is quite nice, a mellow but melodic tune with some terrific guitar solos. It's followed by the album's stand-out track, "There's No Way Out Of Here," perhaps his finest solo moment, a really catchy tune with a killer hook and a penetrating harmonica/guitar that sends a few chills and is as worthy of the classic rock canon as anything else from the late '70s. (Perhaps not surprisingly, it's not an original, but rather a song by relatively unknown band Unicorn, whose album Gilmour produced.) (BTW, Unicorn are worth checking out, middle-of-the-road '70s rock that blends British folk, prog and pop, and is surprisingly good, if a bit on the yacht rock side of things.)
Things are a bit more erratic after that. "Cry From The Street" is a beefy blues rocker that sounds a lot more Bad Company than Floyd; it's noteworthy mainly for the riveting coda reprising the same riff used to close out Animals' "Sheep"; "So Far Away" is a pretty ballad; "No Way" is a haunting track that could almost pass for an Animals outtake (musically), though again there are shades of Bad Company's stiff hard rock; "Short and Sweet" is a solid mid-tempo rocker, with some cool reverb-drenched guitars that presage the sound of The Wall (particularly "Run Like Hell"); "Deafinitely" is a rocking instrumental that is mostly a continuation of "Sheep" with some interesting moog-like jams (just as "Raise My Rent" sounds a bit like a solo re-do of "Dogs").
Obviously, "No Way Out Of Here" aside, this isn't in the same league as the Dark Side/Wish You Were Here/Animals/Wall run, but it's probably the closest any individual member gets to an "essential" solo album for Floyd fans (aside from the two flawed but fascinating Syd Barrett albums).
I don't know if he ever toured behind this, but Gilmour did a few live promo videos for the album. Here's "There's No Way Out Of Here":
