Tuesday night in Detroit Eminem made his grand return to the stage after a four-year absence -- and a stint in rehab for drug addiction -- to celebrate the release of his comeback album, Relapse, with an eight-song set for a crowd of 2,000 fans.

Here's a rundown of the essential albums available online and in record stores today:

He may be freshly out of rehab, but Eminem still knows how to party -- and the Detroit rapper will do just that tomorrow, May 19, with a free concert in his hometown that will celebrate the release of his first album in five years, Relapse.

Three years before Eminem bitch-slapped the hip-hop world with his 1999 breakout album, The Slim Shady LP, the Detroit rapper released his debut, Infinite, as a limited run of only 1000 copies. The long-out-of-print record has since become a rare collector's item -- but now it's available as a free download!

In case you couldn't tell from his bloody, horrific new music video for "3 A.M.," Eminem apparently has a sense of humor.

SPIN cover stars No Doubt played their first concert in five years this week, kicking off a massive summer reunion tour.
