10. ‘For Unlawful Carnal Knowledge’ (1991)

Luckily, we’re already almost done with the ‘90s on our list – a decade that wasn’t all that kind to Van Halen. But first we take a healthy step up in quality with 1991’s ‘For Unlawful Carnal Knowledge.’ Apart from the massive piano-led hit "Right Now," it’s the most straight-ahead, guitar-focused album of the Van Hagar era. The problem is, you find yourself missing the diversity of ‘OU812’ and ‘5150’ a bit.
