Congratulations on using Rishi as something other than an anagram of Irish :)

I’m not sure I’d agree with the musician classification (and I’ve worked for three of the four) - It’s a bit narrow and doesn’t really fit them all. I’d say BI was punk rock and then main stream. Elvis Costello was associated by others with NW - but was really pub rock and Punk . (Stiff stable) I guess NW isn’t strictly wrong but it feels wrong to me :)

Fronted bands is enough

I went with singers surnames.
