He's spot on in the sense that Mark is a quality-oriented artist and cares about his craft and has done so since the early days. No-one can say any of his solo albums are bad, because they simply aren't, objectively speaking. But looking back at his solo career, I do wonder why he wasn't more daring and willing to challenge himself. Step outside the box. It's been a variation on a theme, all the way. He's financially independent and has total artistic freedom, and yet it's almost the same album again and again, with minor twists and tweaks. I'm really curious about what it is that makes him stick so close to the well-known.
I'm not sure I agree with "his albums are all the same". Yes, they do follow a similar formula - some shoe-tappers, some ballads, celtic stuff, bluesy stuff, a bit of country, the occasional rocker - but it's exactly that variety that I find astonishing. I don't know many artists that have such a broad palette. Compare that to, say, J.J. Cale (as much as I like him), and you'll know what I mean.
Now, because there's so much variety within each album, the songs from various album vary just as much. Put Don't You Get It (from Golden Heart) next to One More Matinée (from Sailing to Philadelphia) next to Quality Shoe (from the Ragpicker's Dream) next to 5.15 AM (from Shangri-La) next to The Fish and the Bird (from Kill to Get Crimson) next to Monteleone (from Get Lucky) next to Gator Blood (from Privateering) next to Silver Eagle (from Tracker) next to Heavy Up (from Down the Road Wherever) next to Watch Me Gone (from One Deep River), and you'll have 10 totally different songs.
I totally agree with Railking! He's always had a very wide range of styles, but to me, the music has become much more refined and perfected over the years, to the point where you really have to put on a good pair of headphones to hear all the subtle nuances!
Re "Step outside the box" - I think it's maybe because he IS the box 🤣
I'm convinced that he could've played anything, any style if he had chosen to. I mean, he did a better version of Django on Metroland (took me a while to figure out that it wasn't Django himself, in fact), in various songs there's a better "Hotel California" riff, a better "Another brick in the wall" riff, and many more like that, and he said in an interview once that he liked "shredding it" with his son occasionally, so he could probably out-satriani them all 🤣
But instead he just chose to make his own music, and be true to himself, as Pavel said.
