I'd have to say my perfect albums are, Mudvayne's LD50 and Coheed's In keeping secrets of silent earth 3 and Good apollo im burning star volume 1.
I have consistently listened to Ld50 as well as every coheed album since purchasing them, I cant get tired of mudvayne or coheed. Ryan Martini and Mike todd"s bass playing are both something to behold. Ryan's got mad skills and wide range of style's when it comes to his basslines, I cant wait for their next album to see what he does next. Coheed & Cambria is just amazing all around, their music traverses many genre's and styles while staying unique and familiar at the same time cuz it aint hard to tell what their influences are but they are still original nontheless. Plus Mudvayne's got music you can blow off some steam and bang your head to while coheed is nice to chill to as they have nice melodic songs as well as musically complex songs.
One honorable mention would be Alien Antfarms ANThology, cuz I think AAf is a very underrated band and i love their music, lyrics, bass, guitar, drumming, everythin, plus their songs are in my head all the time, which is probly one of their faults cuz a lot of their music is justg really catchy, nothing more, nothing less.
Another Honorable mention Would be Nonpoints To The Pain, cuz they are a very skilled band and I just love how they put their own latin spin on metal, it makes for some pretty interesting songs to say the least.(this went longer than expected)
