I mean... what's she really talking about here? It seems obvious to me that Morrissey developed as a singer and a lyricist in his solo career. The fine voice that he's in from Your Arsensal especially through to, debatably, Years of Refusal makes his singing with The Smiths sound froggy and weak. I also far prefer him as a mature writer, when he's not appointing himself spokesman for every teenager in the UK as he often did in The Smiths.
It's also apparent to me that the strength of the compositions loses something post-Marr. You just don't come across guitar players like him every day, Boz, bless him, does not have that level of virtuosity. Now, since the Smiths, Marr has gone on to be a superstar session musician, he works in a similar vein to Nile Rodgers. There's nothing wrong with that, although I'd reckon that most people prefer his work in The Smiths to, say, his stuff with Modest Mouse, or his album with The Healers.
Morrissey, meanwhile reached some incredibly high heights as a solo act - I do prefer solo Morrissey but I still like the Smiths. He was on track to be revered and loved along the same lines as Cohen, Mitchell, Dylan, but that'll never happen now. He martyred himself in the name of contentious opinions and fringe political parties, and he's surrounded himself with sinister showbiz figures. He seems to me to be very ill. Marr, meanwhile, gets to float down from heaven whenever he wants, drop a cheerful and safe solo album, and join whichever indie band his kids have introduced him to for a year or two without risking "cancelation" or injury to his bank account. There's no use comparing the two, or lionizing Morrissey solo at the expense of The Smiths, and I think this Dodwell woman should take her articles no one asked for to tumblr or Reddit, the argument she makes is so beside the point.
