This double album features Joplin performing with the freak-flag-flyin' Big Brother and the Holding Company and the aptly named, truly badass Full Tilt Boogie Band. Joplin will forever be known as one of rock music's all-time best singers, and the proof is all over this priceless document. But less celebrated is the fact that she was always backed by bands that literally smoked. Check the topped-out, strangled lead crammed in at 27 seconds into this album, not to mention the fully unhinged freak-out that follows. Meanwhile, Full Tilt play soul like they grew up at Muscle Shoals.
