Running Harlequin's Final Run, Need musical suggestion Options

[Frieza_Prexus]

So I've been running Shadowrun for my current group for about 6 months now, and the very first session I ran the first section of Harlequin for them as an "Introductory Mini-Module."

Ever since then, I've done one "Mini-Module" after every normal run. The players know little about the Harlequin module, and all they really know is that it's a "killer" module. Every time I mention it, they groan with trepidation. None of them suspect at all that this is what they've been running off-and-on since the first session.

I'm now getting ready to run "Present" as they just kidnapped Frosty today. Now, when it comes to mood music, presentation, lighting, props and so on, I'm a huge sucker. When the players finally meet Harlequin, he's wailing on his guitar playing "alternately fast and slow but always powerfully"

The module describes the tune as otherworldly but familiar. I need some 15-20 second clip to play to set the stage for him. It needs to fit the flavor description AND it needs to be something that personifies Harlequin as a character. I've chosen to portray him as a very jaded & dark character who simply uses the Joker shtick to keep his cynicism in some semblance of balance. I plan on developing him as someone who is, quite frankly, ready to move on to the next life, but only his fear and heartbreak at whatever tragedy broke him back in the 4th world keep him from doing it. There's also a small but strong portion of him that feels compelled to step-up and fight for the little guy since no one else (Big D not withstanding) will do it.

I plan to end this SR game in a few months or a year with a massive go at Harlequin's back.

Any suggestions on the music? I've been tossing around a few ideas in my head from Highway to Hell to Dream On, but I just can't find it.
