A Little Older, A Little Wiser You have a good track here, but let me elaborate a little more:
I know what you meant when you said you loved the vibe of this song -- something I think other listeners will be able to relate with as well. It gives me a calm, chill, and almost soothing vibe; and I can explain this a little better: the bass and the lows in general do overpower everything else and sounds like it's kept under the ceiling by a limiter. This is actually something I like about the lo-fi experience, and I don't know why; but it seems to ease tension in my head if that makes sense.
I think your choice of instruments were superb, in particular the constant guitar and the vocals in the background -- really good taste and was like salt and pepper to an already good meal.
Critical Analysis:
One thing that bugs me with all chillout tunes is the fact that they are so repetitive (however the same could be said for just about everything that is released today). I can understand instances where a composer lacks computer power or resources to do too much at once, but I felt as though this track was confined to a specific pattern that it couldn't deviate from.
The instruments are all good at what they do, but I felt like at least a new lead instrument could be introduced around 2:19 when the percussion and bass comes back in, or maybe do something even more crazy and keychange to lead up to the fadeout.
Final Thoughts:
I feel like this song has actual marketing potential. However I already know that if an advertiser would hear it, they would get somebody to EQ it, master it, and replace the bass; but as for me I like it just the way it is. Heck man, I think this would be great to listen to while you're studying or relaxing in the evening after a long day.
What I'm going to say here is off the record and did not impact my score:
You are one of the best Newgrounds musicians we have. It's not because of what you produce, but it's because of the support you give to the community as a whole. Most musicians are out for themselves, but our community thrives when we have users like you who are more than willing to encourage others. Music is one of the toughest businesses to get into, and I don't know what I would do if I didn't have my Newgrounds community to go to; so don't ever get too discouraged out here. Remember that there are people here who support you because you support us.
