We’ve reached Day 8 of TVLine.com’s American Idol All-Time Greatest Performance Bracket Tournament — the final quartet of first-round matchups. The eclectic lower half of the Pop/Rock/Country Divas division contains two memorable Janis Joplin covers, two terrific renditions of Heart’s “Alone,” and a couple of piano-playing troubadours tackling classic British bands.

Yes, folks, we’re taking you back to “Cry Baby,” “Me and Bobby McGee,” “Let It Be,” and “The Scientist,” among others, as part of our 64-player tourney, which is composed of the most electrifying moments in the 10-season history of Fox’s ratings behemoth. It’s your job to vote in these single-elimination faceoffs, and decide which 32 Idol Moments advance to Round 2.
