Trip Hop is electronic music mixed with Trance, Techno & Hip Hop elements. It is perfect for people who like upbeat music but don't enjoy listening to the top 100 while they practice. If lyrics in music distract you or your class, you can find many trip hop artists who use very few words, if any, in their compositions. Here are a few of my favorites.
Group: Little People/ Album: Mickey Mouse Operation
Group: Bonobo/All Their Albums are Usually Good
Group: Massive Attack/Albums: Heligoland & Mezzanine.
