Tonight's "12-12-12: The Concert for Sandy Relief" promises to be one of the biggest events in music history. It will likely be one of the most viewed events in the history of the Internet, too.
The concert features Bruce Springsteen and the E Street Band, Paul McCartney, the Rolling Stones, and many other A-list rock artists. Between TV and radio broadcasts and online streams, organizers expect to reach more than 2 billion people worldwide.
Springsteen is set to kick off the show at 7:30 p.m., ET, and if you don't want to miss a moment, you can find streams on at least 30 different sites, including Facebook, Myspace and Hulu.
If quality matters, you may want to opt for a site that you know can handle the traffic. On the other hand, you may want to pick a site that draws people with similar tastes. However you want to dial in, there's an option for you.
Most dependable: YouTube is known for on-demand video, but it has plenty of experience with live-streaming, too. In October, Jay-Z live-streamed his concert from Brooklyn on YouTube, and last year you could watch a Coldplay concert from Spain live. The site certainly has the muscle to handle a large number of simultaneous streams.
For the younger set: MTV.com will offer a stream, as will Fuse.tv. You can bet that the online chatter on those sites will skew well younger than the average age of the artists on stage — the lineup is steeped in classic rock.
Oddest couple: If you happen to be a basketball fan and music fan, check NBA.com. You can follow the scores of tonight's games while watching the show. No word on whether Charles Barkley will provide critiques of the bands' performances throughout the evening. [See also: Top 5 Basketball Apps to Tip Off the NBA Season]
Audio only: If you can't spare time to watch the concert, maybe you can listen anyway. ClearChannel, the company that owns thousands of radio stations across the country, will stream the concert on its sites, including iHeartRadio.
Read all about it: Twitter will be active with messages about the concert. If you don't have time to dedicate to watching the whole show, follow the hashtag #121212concert to get live tweets of who's playing and then tune in for your favorites.
