Anyway, to address your original question...
Attitude is ok, but
Shadowbeat should be your "Go To" book, IMO.
There are also a couple other adventures that involved Rockers (
Total Eclipse and
Dark Angel), as the idea of "Rock n Roll can Save the World" was still big back in the early days of SR, and musicians still had a bit of that "bad boy/girl rebel" image to them that fits Shadowrunners so well.
Plus there's
A Killing Glare, which is a psuedo-sequel of sorts to
Mercurial (It involves some of the same enemies/antagonists) and deals with one of Shadowrun's made-up future sports, Urban Brawl. More info about UB can be found in
Shadowbeat, and also gets some detail in a German created sourcebook (that is sadly only available in German) called
Blut & Spiele (I think that's how it's spelled, and translates as Blood & Games, I think).
The old Roc Novel (long out of print and not available digitally due to... issues)
Dead Air by Jak Koke deals with Combat Biker, another Shadowrun original sport.
The third edition book
Sprawl Survival Guide has a little bit talking about reporters as well, though I think that's delving outside your original question a bit. (Rockers, Sports Stars, and Reporters were the key things covered by
Shadowbeat, so I always lump them together
