But back to a cappella. This is one of my favorite genres. I'll drop in a few groups, one per post.
First,
The Bobs. They've been around for over 20 years, and still sound incredibly modern. Their songwriting abilities are incredible, and have songs about the strangest things. Downloads from their website include
Hidden Bonus Track (yes, that's the actual title, and it isn't hidden on the album either) and an amazing cover of
Helter Skelter.
Most of the time, The Bobs are three men and one woman. The cast has changed over the years, but they always sound like The Bobs. I recommend "My, I'm Large" as a first album to purchase, followed by "Coaster".
