Spencer & Hill

If you like electro house with great vocals, then your'e gonna like Spencer & Hill. Another Germany-based pair of artists, Spencer & Hill have so many different aliases that its sometimes difficult to know who made what your'r listening to. Manuel Reuter (Josh Hill) is part of Cascada, Liz Kay, MYC, Plazmatek, and a host of others, and I don't know much about Manuel Schleis (Spencer). Whatever their names are and whatever they work on, its the end result we're interested in and Spencer & Hill is rock-solid. 
Their Compilation mixtape, 'Housebeats 1' came out last January, and there are rumors that Housebeats 2 might be coming out this January, so here's hoping. Their latest album, 'The Funky Years', was released in September, and I suggest you get that. If you're broke, please tune in here:
Spencer and Hill have a thing for remixing R.I.O.
R.I.O. - Shine On (Spencer & Hill Remix)

R.I.O. - When The Sun Comes Down (Spencer & Hill Remix Club Edit)

R.I.O. - Rio (S & H Project Remix)

Considered by some to be the best when it comes to electro house, Spencer & Hill's tracks are undoubtedly energetic, and if you're having house party, as in a party in your house, this is the stuff you wanna be rocking out to.
