American bands have never gotten in the habit of their British counterparts, who tend to release lots of extended singles filled out with not-meant-for-prime-time experimentations. If the Beasties had gotten into that habit, this would be their B-side compendium: a dozen instrumental tracks showing off their groovier side, complete with plenty of wah peddle on the guitar and prominence given to frequent Beastie collaborators "Money" Mark Nishita (keyboards) and Eric Bobo (percussion). It's tough to believe that the same band is responsible for this and the Aglio e Olio EP, but it goes a long way in explaining how they've remained viable for so long.
