I BET ON SKY is the third Dinosaur Jr.. album since the original trio - J Mascis, Lou Barlow and Murph - reformed in 2005. And, crazily, it marks the band's 10th studio album since their debut on Homestead Records in 1985. Back in the '80s, if anyone has suggested that these guys would be performing and recording at such a high level 27 years later, they would have been laughed out of the tree fort.
