Working through Michael's great 'Unaccompanied Django' book gave me a renewed interest in unaccompanied pieces. I found this link to an Eddie Lang transcription of 'April Kisses'.
Listen to the tune and you can understand why Django was influenced by him. Another piece is 'Jeannine ( I Dream of Lilac Time), still looking for a transcription of that one. He did a few others too that are simply amazing displays of his skills. You can find these tunes on his 'Handful of Riffs' CD, available in the new store:
And BTW, if you get a chance, buy Michael's book. 8)
