I own every Angra album. Been listening to them for years. Sound has changed over time though. I personally prefer the old sound, when Andre Matos was still the lead singer. He brought a whole lot to that band besides just his voice. However I think Edu was a great replacement for him, and Angra is still a great band. They both have that same Angra sound, but if you pay attention you can really tell the difference between the Andre songs, and the Edu ones. The songs just had a different sound. Compare songs like Carolina IV, and The Shaman, Metal Icarus, Angels Cry, and Make Believe (all with Andre) to some more recent ones such as the entire temple of shadows, or rebirth albums.
Some of my favorites from Angra (not including what you listed) would have to be...
Metal Icarus
Carry On
Make Believe
Carolina IV
Running Alone
Acid Rain
The Shaman
The also did some good covers in their time. Such as "Painkiller" (Judas Priest) and "Kashmir" (Led Zeppelin). Check out the discography, there are good songs littered throughout it, by both Andre and Edu.
Although not Angra, check out "Fairy Tale", or "Reason More", by a band called Shaaman. That's where Andre went after he left Angra. Now he just released a solo record. But I haven't heard it yet. Also if you like instrumental at all. Give a listen to Kiko Loureiro's solo album. He is the main guitarist of Angra.
