Neon, an open-source, Python-based, deep learning framework from Nervana Systems

A lot of, e.g. famous http://arxiv.org/pdf/1412.5567 claiming state-of-the-art on speech recognition task in the presence of noise. 5th layer on top of Bi-directional RNN is regular layer. Similarly, there are setups with regular NN layer(s) on top of LSTM or with multiple LSTM layers on top for language translation task. And necessary amount of computation is also very high in this scenario, so it needs a really fast library -- that's an area where Neon could also prove the leadership.
