What Wide/Ultrawide Lenses Would Be Best For Me?

[ptvredwings]

I currently only have a 24-60mm, and 50mm lens right now and needing a wider lens while I'm closeup in an intimate venue for live music shots along with being in close tight areas with my subject in other occasions while needing to get more background in. The only catch is it has to be a zoom and at least f/2.8 if not better. Ultrawide would just be nice for fun creative pieces. Which Canon lenses can I choose from that would do well on a cropped sensor?

Canon 17-55mm f/2.8 EF-S IS USM sounds like it'd be a good lens.
