There are several bands called Swallows:

A) Swallows is Sian Macfarlane from the weirdest core of the Midlands. Inspired by rainfall, speaking backwards, creeped-out ambience and clustering samples her music seems to draw a lot from a playful recording techniques whilst guitar and/or keyboard lines swell and underpin the songs, often accompanied by some extra dissonance and her ghostly vocal.

B) “Swallows is an alternative band out of Minnesota that has invoked what people are calling 'rock and roll, ugly and beautiful, profane and spiritual.' This quartet brings a blend of classic blues, a barrage of eclectic instruments, and warm yet gritty Nick Cave vocals.” - David Buchanan, Consequence of Sound
Swallows' line-up features the collaborations of Jeff Crandall, Aaron Kerr, Tyson Allison and Frank Spencer. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
