It's the moment many U.S. fans have been anxiously awaiting since Black Sabbath announced their reunion plans with Ozzy Osbourne on vocals, and the group's Lollapalooza performance was definitely a triumph.

The original lineup (minus Bill Ward who is still holding out over a contract dispute) took the stage at Chicago's Grant Park for their only scheduled U.S. appearance this year, and they were greeted with a rather huge and pumped-up crowd.

The band opened the show with the song that shares a name with the band, 'Black Sabbath,' with the audience going crazy. Beyond that, the group kept things lively with 'The Wizard,' featuring a masterful Ozzy on harp, 'Beyond the Wall of Sleep,' and 'N.I.B.'

During the hot and humid Midwest evening, singer Ozzy Osbourne's voice may not have hit every note, but our reporter on the scene told us that he more than made up for it with the showmanship, enthusiasm and boundless energy during the show.

One of Ozzy's most human moments ironically came during the band's performance of 'Iron Man,' in which he ran over to kiss the woman who was offering a sign language translation for the deaf audience members and managed to keep up with the band throughout.

Another highlight from the evening came during the instrumental 'Symptom of the Universe,' with each of the band members catching a bit of a much-needed breather while drummer Tommy Cluefetos performed his drum solo for the crowd.

As the solo began to wind down and the band members returned, the skin-pounder transitioned the group into the opening beats of 'Iron Man.' 'Fairies Wear Boots,' 'Dirty Women,' and 'Children of the Grave' followed before the encore, with the night's festivities ending with 'Paranoid' and the crowd exiting the venue satisfied.
