Various Artists, Brown Acid: The Tenth Trip
What It Is: The curators of the 10th volume in this great series once again dig up obscure hard-rock tracks from the '60s and '70s that were just a little too loud and dirty to make local playlists at the time. Some are still ahead of their time.

What's on It: The 10 songs here come from Denver, Atlanta, Louisville, Canada and other North American locales where kids were armed with weed, guitars and too much time on their hands. This is the sound of garage-rock skirting the lines of metal.

Best Song You Know: Chances are you probably haven't heard any of these songs, unless you were friends with the bands back in the day (or maybe even in one of the groups). The best is Sounds Synonymous' riff-heavy "Tensions."

Best Song You Don't Know: Like most Brown Acid compilations, the songs and artists on The Tenth Trip can sorta bleed into one after about 15 minutes, but there's no shortage of awesome tracks here. You won't know them, but crank the volume anyway.
