Just adding to what has been said: if the subject (with the words "banda"/"grupo"/"cuarteto", etc.) is not explicit, we rather tend to talk about the members of the band. (Which I tried unsuccessfully to show in the paragraph I invented.)
However, keeping the subject doesn't harm:
Queen era una gran banda. Ahora (la banda) está de gira sin Freddie.
Queen era un gran grupo. Ahora (los miembros del grupo) están de gira sin Freddie.
