PLEASE. LISTEN. TO THIS. PURE. AWESOMENESS.
And do buy Pentatonix's album, PTX Vol. 2 if you haven't! It's really worth it, and very difficult to stop listening to. Compared to their first album, I think Vol. 2 really shows a strong sense of musical maturity and direction. The originals are very solid while the covers are groundbreaking - I was especially impressed by "Valentine", because their cover is just SO much better than the original (which was honestly quite disappointing). This is certainly one of PTX's many strengths: taking an actually rather ordinary song and digging out its potential/revitalising it through a very refreshing reinterpretation.
"Run To You" will definitely please the choral fans with the lush chords and harmonies. The Eric Whitacre influence is certainly very strong in this one. I also really enjoyed Mitch's catchy sliding falsetto chorus in "Love Again" and the constant switching between major/minor tonality; very clever, especially when they switch to major on 'novocaine' and 'morning sun'.
In short, it's an amazing album. Go get it.
