```
[ngStyle]="{'background': 'url('+artist.images[2].url+')'}"
``` | You missed something here, Angular needs double curly braces to render scope variables in the template (when you won't use it in the directive, such as ngIf, etc.):
```
<div *ngIf="artist.images.length > 0">
<div style="background-image: url("{{ artist.images[2].url }}")">
</div>
</div>
