Van Halen teams with Tiger Jam, Jay-Z with Mary J. Blige

Van Halen gigs are always for a good cause, namely, getting loaded.

But when the band headlines Tiger Jam on Saturday, it all takes on a whole new meaning, as proceeds from the show go to benefit a variety of charities.

Know what that means?

Basically, by knocking back a mess of brews and belting out "Panama" at the top of your lungs like an inebriated bullhorn, you will be helping your fellow man.

Leave it to "Diamond" David Lee Roth to help you get in touch with your inner Mother Teresa.

See the band at Tiger Jam XI at 8:30 p.m. Saturday at the Mandalay Bay Events Center, 3950 Las Vegas Blvd. South. Tickets are $133.25-$185.75; call 632-7580.

It's like Bonnie and Clyde, except with fewer bullets and more songs about big pimpin'.

In one of the biggest urban music pairings in recent memory, hip-hop mogul Jay-Z has teamed up with bawdy R&B siren Mary J. Blige for the blockbuster "Heart of the City Tour."

Together, they've sold more than 70 million albums, won 12 Grammys and made enough bank to rival the GDP of Uganda.

She's the tough-yet-vulnerable soul sister, he's the big-talking MC with a vocabulary so sharp, it's as if it were spun from barbed wire.

Seriously, this is the best pairing since beer and breakfast.

See them at 8 p.m. Saturday at the MGM Grand Garden arena, 3799 Las Vegas Blvd. South. Tickets are $83.70-$210; call 891-7777.
