It's quite an interesting list with some artists on there I didn't have on my list, but could quite easily have done. 10cc were one I overlooked - what a superb Manchester band they are. I've had plenty of discussions over the years with people who think only Oasis, Stone Roses and the Happy Mondays are Manchester bands. 10cc are immense and I love the variety of work and just general quirkiness. They are criminally underrated.
Deep Purple are another band I really like but didn't have on my list, they've done some absolute belters over the years.
I'd heard stuff by Sleaford Mods and thought they were ok, but nothing special, but for 4 people to vote for them I might give them another go.
I did wonder if we'd have any rap on there - it's quite "guitar/rocky" overall.
If nothing else, these threads have been great for discovering new music!
