Is it just me, or is no-one else really excited to see Mark and David Gilmour together? This is a rare event, a meeting in a studio of two of the true greatest guitar players ever!! The contribution these two have made to music over the last 50 plus years is immense. It must have been something to hear Gilmour playing at British Grove, and lucky for Guy to have recorded him. Assuming the song is written by Mark, that is amazing to finally have Gilmour playing on one of Mark's songs. The photo is rare too, I know they must have run into each other over the years, but a photo together is not something you see. They both played at Knebworth 1990 and the famous French and Saunders sketch. David has been to watch Mark in concert I believe, and has commented how much he like Mark as a player, I don't think I have heard Mark say anything about David though, clearly he must think he is a great player, but I have not heard him mention David or Pink Floyd. It's funny, you don't think they have much in common as players, but they do, they are both heavily in the Blues, and both have recorded with BB King. Mark and Eric Clapton compliment each others playing, so, I could imagine these two doing the same thing, they are both highly melodic players, and each of them play with an exquisite touch and feel.
I do have an article where MK was asked his opinion about DG and DG about Gilmour I can sum it up from memory.
Gilmour was clearly the most impressed, he quoted songs like BIA, Romeo and had a very nice word about MK's technique and said he could never be able to play some of his licks.
MK explained that DG was a great guitarist because he had the ability to improvise around melodies without playing the melody itself in a straightforward way or something of the kind. When I have time I'll scan the article it's French but deepl can help.
